How to Unlock a Cell Phone and Enabling Roaming

Introduction
Cell phones have become an essential part of our lives, keeping us connected with loved ones, work, and the world at large. However, if you are traveling internationally and want to use a roaming SIM card, you need to unlock your cell phone and enable roaming. Unlock a cell phone to use it with different carriers like OneSimCard. Enabling roaming ensures that you can use your phone’s services when traveling abroad. In this comprehensive guide, we will discuss how to unlock a cell phone and turn on roaming for International use.
Part 1: Unlocking Your Cell Phone
Unlocking a cell phone is a process that allows you to use your phone with different carriers, providing you with more flexibility and cost savings – especially when roaming internationally. Here’s how to unlock your phone:
1. Check if your phone is eligible:
Not all phones can be unlocked, and the eligibility criteria may vary from carrier to carrier. Typically, you need to have fulfilled your contract or paid off the device, and your account should be in good standing.
2. Contact your carrier:
Reach out to your current carrier to inquire about unlocking your phone. They will guide you through the process and provide specific instructions based on your phone’s make and model. Carriers often have online forms or customer service hotlines for unlocking requests.
3. Use a third-party unlocking service:
If your carrier is uncooperative or you’re unable to meet their criteria, you can consider using a third-party unlocking service. There are many reputable companies that offer unlocking services for a fee. Make sure to do your research and choose a reliable service.
4. Unlocking through software:
Some phone models can be unlocked using software tools or codes that are readily available online. However, this method can be risky and might void your warranty or damage your device, so proceed with caution.
5. International use and traveling:
Ensure your phone is compatible with the networks in the country you’re visiting. We often hear from customers that their phone isn’t connecting and this is because they have a phone that isn’t compatible in that country with the frequencies being used by the carriers in that country. Be very careful and do your research!
6. Check for limitations:
Some unlocked phones may have limitations, especially if they were originally carrier-branded. For example, some carrier-specific features or apps might not work on a different network.
7. Complete the process:
Once your phone is unlocked, you will receive a confirmation message or notification. At this point, you can insert or download a SIM card from OneSimCard and enjoy the benefits of a more flexible phone.
Part 2: Enabling Roaming on Your Cell Phone
Roaming allows your phone to access cellular services from other networks while you’re in a location where your carrier doesn’t have coverage. Here’s how to enable roaming:
1. Contact your carrier:
The simplest way to enable roaming is to get in touch with your current carrier. They can activate it for your account, and you’ll receive instructions on how to enable or disable it on your phone. Be very mindful of excessive roaming fees from your carrier, especially when traveling internationally.
2. Check roaming packages:
Carriers often offer international roaming packages that provide reduced rates for calls, texts, and data when you’re abroad. Inquire about these packages and choose one that suits your needs if you plan to travel frequently.
3. Enable roaming on your phone:
The exact steps to enable roaming may vary depending on your phone’s operating system (iOS, Android, etc.), but generally, you can find it in your phone’s settings. In most cases:
For iOS devices, go to “Settings,” then “Cellular” or “Mobile Data,” and toggle the “Data Roaming” option.
For Android devices, navigate to “Settings,” “Network & Internet,” and “Mobile network,” then enable “Data roaming.”
4. Be mindful of data usage:
Roaming can be expensive, especially when it comes to data usage. To avoid unexpected charges, monitor your data usage closely, and consider disabling data roaming when not needed.
5, Understand call and text charges:
While roaming, calls and text messages may also incur extra charges. Check with your carrier for details on the rates and consider using messaging apps and VoIP services like OneSim VoIP to reduce costs. We talked about using VoIP in a previous post here.
6. Use Wi-Fi:
Whenever possible, connect to Wi-Fi networks to save on data usage. Most places around the world offer free or paid Wi-Fi services, which can be a more cost-effective way to stay connected.
7. Prepaid SIM cards:
In most cases, it is more cost-effective to purchase a prepaid SIM card in before you go abroad. This allows you to use your device while roaming internationally for less cost than using your carrier’s roaming plans. For example, if you are using Verizon in the USA, they charge $10.00 per day for international roaming plans. If you are going to the EU for 2 weeks, this will cost $140.00. With OneSimCard, you can purchase an eSIM with 10,000MB for 14 days for $59.00 + $9.95 for the eSIM…a HUGE Savings!
8. Stay informed:
Keep an eye on your phone’s signal strength and check that you are connected to a network. Ensure that you have a roaming signal.
9. Deactivate roaming when not needed:
To save on battery life and prevent accidental data usage, turn off roaming when you’re back in your home country or in an area with good network coverage.
Conclusion
In conclusion, unlocking your cell phone and enabling roaming are important steps to ensure you can use your device more flexibly, both at home and when traveling. By following the guidelines in this comprehensive guide, you can navigate these processes with ease, enjoying the convenience of staying connected wherever you go, while also being aware of potential charges and best practices for using your phone abroad.

What’s the Best Choice: Cellular Voice vs VoIP When Traveling?

Introduction to VoIP When Traveling
Voice over Internet Protocol (VoIP) has revolutionized the way we communicate, offering a cost-effective alternative to traditional cellular voice calls, especially while traveling. In an era where connectivity is essential, VoIP has emerged as a powerful tool for staying in touch without breaking the bank. Here, we explore the reasons why using VoIP is less expensive than cellular voice when traveling, delving into the economic advantages and technological advancements that make VoIP the smarter choice for globetrotters.
Cost Savings: A Primary Consideration
Traveling often means navigating different cellular networks and international roaming fees. Cellular voice calls can become exorbitant, with carriers charging substantial rates for international usage. VoIP, on the other hand, utilizes the internet to transmit voice data, bypassing traditional phone networks and their associated fees. Services like Skype, WhatsApp, and Zoom allow users to make voice calls for free or at significantly reduced rates compared to cellular providers. Cellular providers range wildly depending on the country and provider. We see costs range from $0.30USD to over $2.00 per minute for cellular voice, but a minute of voice is typically less than 1MB and we see international roaming rates under $0.01/MB for data. This upfront cost savings is a compelling reason for travelers to opt for VoIP.
Global Connectivity Without Borders
VoIP operates over the internet, making it a borderless communication solution. Unlike cellular voice, which requires compatible networks and roaming agreements, VoIP connects users seamlessly regardless of their geographical location. This feature is especially beneficial for travelers, as they can maintain communication with friends, family, and colleagues without having to worry about international restrictions or network compatibility. Whether on a business trip or a leisurely vacation, VoIP ensures uninterrupted connectivity at a fraction of the cost.
Wi-Fi Dominance
Modern travel destinations, whether hotels, cafes, airports, or public spaces, invariably offer Wi-Fi connectivity. VoIP leverages these ubiquitous Wi-Fi networks to establish voice connections. Travelers can take advantage of free or low-cost Wi-Fi options to make VoIP calls, eliminating the need for expensive cellular voice plans. This symbiotic relationship between VoIP and Wi-Fi amplifies the cost-saving benefits, allowing users to communicate conveniently without the burden of extra charges.
Inclusive Services
VoIP services frequently bundle features that further enhance their value proposition. Video calls, text messaging, and multimedia sharing are often included alongside voice calls. Such comprehensive services eliminate the need for separate applications and subscriptions, simplifying the communication process for travelers. In contrast, cellular voice calls typically offer limited additional functionalities at higher costs, making VoIP a more versatile and budget-friendly choice.
Advancements in VoIP Technology
The continual evolution of VoIP technology has solidified its position as a cost-effective alternative to cellular voice. High-speed internet connectivity has become more accessible and reliable worldwide, ensuring stable VoIP connections even in remote locations. The development of codecs and compression algorithms has optimized voice data transmission, reducing bandwidth requirements and enhancing call quality. These technological advancements contribute to VoIP’s cost-effectiveness by minimizing data consumption and maximizing the efficiency of voice communication.
Evolving Smartphone Apps
Smartphone apps have become integral to modern travel, offering navigation, translation, and currency conversion at the touch of a button. VoIP applications have seamlessly integrated into this ecosystem, enabling users to make calls directly from familiar platforms. As these apps continue to improve their user interfaces and functionalities, travelers find it increasingly convenient to use VoIP for their communication needs. The integration of VoIP with other essential travel apps further solidifies its cost-effective appeal.
Not All VoIP Apps Are Equal
OneSimCard developed the OneSim VoIP app for their customers to make VoIP when traveling even easier. Our coverage, usability and rates are the main benefits of our VoIP app. Even if, by rare chance, you happen to find yourself in a place where our SIM card has no service, you can use Wi-Fi with our VoIP app with your Personal Extra Number (PEN).
Our VoIP app also doesn’t require the other person to have the same app. You can use the OneSim VoIP app to call any phone in the world. Unlike other VoIP apps like WhatsApp, Facetime, etc. the person you are calling, or getting a call from, is just any phone…no special apps needed.
Using the OneSim VoIP app is also very cost effective. Wherever you are in the world the cost to recieve a call is only 1¢/minute. Outgoing calls depend where you are calling to. USA and Canadian numbers, for example, are only 2¢ per minute to call. The best news is calling between OneSim VoIP users is absolutely FREE!!
Customization and Flexibility
VoIP services often provide customizable plans tailored to different user needs. Travelers can select pay-as-you-go options, prepaid plans, or subscription-based models, allowing them to choose the most suitable and cost-effective arrangement. This flexibility empowers travelers to manage their communication expenses efficiently, avoiding the unpredictability of cellular voice charges.
Security and Reliability
Security concerns associated with VoIP have significantly diminished as encryption and authentication technologies have matured. Many VoIP services now offer end-to-end encryption, ensuring the confidentiality of voice calls and data transmission. Moreover, the reliability of VoIP has improved over time, with enhanced call quality and fewer disruptions. Travelers can confidently rely on VoIP for important conversations, knowing that their communications are secure and dependable.
Conclusion
In the realm of modern communication, VoIP has emerged as a cost-effective alternative to cellular voice, particularly when traveling. The substantial cost savings, global connectivity, reliance on Wi-Fi, inclusive services, technological advancements, and evolving app ecosystems collectively position VoIP as the more affordable and practical choice for travelers. As the world becomes increasingly interconnected, embracing VoIP while on the move presents a compelling case for those seeking effective communication solutions without the burden of excessive expenses.
Planning a trip soon? OneSimCard offers both Physical SIMs and eSIMs for all of your needs when traveling internationally. We also have a custom VoIP app available for Android and iOS devices. The OneSim ViOP app, coupled with our Personal Extra Number (PEN) will let you stay in touch with family and friends regardless of where you travel. Our SIMs will also work with your favorite VoIP app, like WhatsApp, Facetime, FB Messenger, Telegram, etc., if you already have one.

The Magic of Mendoza, Argentina & the Vendimia
Selection of Malbec wine bottles on display
Are You planning travel to Argentina? Thinking about places to visit and when to go? We have a great recommendation for you! One of the most important festivals in Argentina takes place at the end of February through the first week of March. The Fiesta Nacional de la Vendimia (The Grape Harvest National Festival) celebrates the most important export of Mendoza, and perhaps all of Argentina…wine.
Settled in 1561 by Pedro del Castillo, the city of Mendoza is a relatively small city. It even feels smaller because of it’s quaint tree lined streets, and welcoming locals. The population of Mendoza center is 115,000 but climbs to 1 Million if you include the “metro” area. It encompasses 21 square miles and sits at 2,400 feet above sea level. The region is best known for it’s wine and olive oil production, especially for growing Malbec grapes. Because of it’s diverse terroir, Mendoza boasts some of the best Malbec wine in the world. Its varying bouquets are based on assorted soil, altitude and temperatures. Grapes are grown here from 2000 feet to 5000 feet above sea level. Nicolas Catena Zapata is the person who pioneered growing at such high altitudes since 1994.
The Vendimia
The Vendimia attracts thousands of South American artists, tens of thousands of tourists (especially wine enthusiasts) to Mendoza. They celebrate all 18 of the provinces that make up the State of Mendoza.
Celebrations aren’t limited to just this time, though. All through the month of February each of the 18 provinces of Mendoza have celebrations and ceremonies related to the wine harvest. This time of year is very special for the entire region. You will be able to have very unique experiences during the wine crush. We suggest roaming around the outlying areas of Mendoza center too. Enjoy lots of wine tastings, rent bicycles or hire a driver and take a tour of the whole region.
This year the schedule of the Vendimia is from February 26 through March 6th:
February 26th – ‘Blessing of the fruits’ ceremony.
March 3rd – 1st parade of Vendimia ‘Queens’ competing for the title of “Queen of Vendimia”, crowding the city streets, throwing fruit and even giving out bottles of wine.
March 4th – ‘Carousel of Vendimia’ This is a morning time parade featuring cowgirls in traditional outfits on horseback
Night of March 4th – The ‘Central Act’ is a fabulous production including over 1000 participants, and ends with the coronation of the ‘Queen of Vendimia,’ and with fireworks from the nearby Cerro de la Gloria in General San Martin park. This is the quintessential celebration when Mendocinos (what the locals refer to themselves as) and visitors take to the streets and parties to share the local elixir.
March 5th –This is a repeat performance of the previous night with additional Argentinian and international artists.
March 6th– A third night repeating the grand finale celebration with additional national artists.
Getting There
Depending on your itinerary you can fly into Mendoza ‘s international airport “Aeropuerto Internacional Gobernador Francisco Gabrielli” (MDZ). This traveler chose to first fly into Santiago, Chile where we stayed a few nights to explore that area before flying from Santiago, over the Andes, to MDZ. Argentina also has great bus lines, and there are even first class lie flat seats available from Buenos Aires for less than $100…but make sure to book a window seat to get great views of the countryside!
Your time in Mendoza and South America will be very memorable, and you will want to stay in touch while you are there. Be sure to get connected using the OneSimCard Universal E international SIM card or the eSIM World E international SIM card. Data rates in Argentina start at $13.00 for 500MB plan on the eSIM World E international SIM card for travelers.

The climate of Switzerland is as varied as its population. There are three main geographies of Switzerland. The Alps, the Swiss Plateau, and the Jura mountains. Most of the population reside on the Plateau where all of the major cities are located. The climate is temperate, but ranges wildly depending on the locality. You will find year-round snow and glaciers in the mountains, but also palm trees in the southern plateau.
Regions
The Alps
The Alps are among the highest and most rugged mountains in the world. The highest peak is Dufourspitze. It is the second highest in Western Europe at 4,736m and is a challenge for any climber. They were formed by the collision of the African and European plates, and continue to grow.
Besides climbing, the Alps are home to a myriad of winter sports like skiing (alpine and cross-country), sledding, snowboarding, and summer sports like para-gliding and skydiving. For the less active, the valleys in the Alps offer absolutely stunning vistas and easy hikes. One of the favorites is the Lauterbrunnen valley. Lauterbrunnen is home to the highest railroad in Europe (Jungfrau Railway), taking you to the peak of Jungfraujoch at 3,454m.
The Plateau
The Plateau is where you will find all of the major cities and beautiful lakes. With Zurich and Basel in the north, Bern centrally located and Geneva in the South, the Plateau is a collection of rolling hills, lakes, rivers and culinary delights like cheese and chocolate. (We recommend a trip to the picturesque town of Gruyere where the cheese is king and the views are stunning. kick back and enjoy some fondue!)

Lake Geneva is easily the most famous of the large lakes, but Lakes Zurich, Lucerne, and the twin lakes of Brienz & Thun are all equally beautiful. If you visit the twin lakes, stay in Interlaken and you will have easy access to both lakes! You can enjoy swimming, boating and hikes around the lakes.
The Jura
The Jura mountains aren’t as famous as the Alps, but that doesn’t mean they aren’t worth visiting. It is the demarcation between France and Switzerland. The Jura aren’t as tall and rugged as the Alps, but there is still lots of great opportunities for hiking, climbing, skiing, and cycling. This region is also known for its watchmaking industry. You can even be an “Apprentice for a day” and build your own watch!
The people of Switzerland are as varied as its geography. The landlocked country boarders France, Italy, Germany, Austria and Liechtenstien. This mixing of cultures creates a diversity in language as well as food, Local dishes are pulled from all of these countries and tend to align country to which that canton is closest. For example, one of our favorite lasagnas was enjoyed in the south, closer to Italy, while in Zurich we had fantastic bratwurst closer to Germany. This melding of cultures also shows in languages spoken, and traditional dress.
Getting Around
When travelling to Switzerland from international origina you will typically Fly into Geneva or Zurich. You may also find flights into Bern, but this is smaller international airport, and is typically used on a regional basis. Once you are in country, the train system is a fantastic way to get around. The trains run remarkably on schedule and are always clean and modern. You will find that the local trains are also used by schools to transport their students, so don’t be surprised to share the ride with lots of kids.
Speaking of trains, we recommend the GoldenPass Line for sightseeing. The GoldenPass trains are designed with huge windows so you won’t miss a bit of scenery. There are 3 main lines: 1) Montreaux > Zweissimmen, 2) Zweissimmen > Interlaken Ost, & 3) Interlaken Ost > Lucerne. You can break up the trips stopping for a night or two in certain areas (we highly recommend the Lauterbrunnen Valley) and enjoy what these localities have to offer. You can also join an organized tour who will handle all of the bookings and activities along the way.
Summary
Switzerland is a truly majestic country with varied geography and cultures. There are many, many activities to enjoy year-round for people of all ages and physical abilities. We recommend travelling in June or July for the best weather. So grab your passport, pack your binoculars to make sure to see all of the stunning vistas and don’t forget your OneSimCard eSIM World or standard global roaming SIM card (the Switzerland SIM card we recommend is the Universal card) because you will want to stay connected to share all of your memories!
