For the first time in nearly two years, Australia has reopened its borders to international travelers.  

More than 50 international flights reached the country on the opening day of February 21, 2022, including 27 touching down at Sydney, its largest city.

Tourism is one of Australia’s largest industries, valued at more than $55 billion and employing about five percent of the country’s workforce. However, the sector was hit hard after the country closed its borders in March 2020.

Australia, a former proponent of COVID’s suppression strategy, has moved away from frequent checks and lockdowns after reaching higher levels of vaccination. Skilled migrants, international students and backpackers have been allowed to fly to Australia since November as part of a reopening exercise.

More information about the vaccination requirements for entering Australia can be found on the official website.

When in Rome, Roam as Savvy Travelers Do.

Rome, Italy
Rome, Italy

Although there is no real off-season in Rome, fall is known for decreased tourist crowds with plenty of sunshine for walking around. The challenge is to experience all the city has to offer. Here are a few picks of essential attractions to get you started.

Being over 2700 years old, the Eternal City combines ancient, baroque and modern eras, which can be both magnificent and overwhelming. A testament to the architectural skills of the ancient Romans – the Coliseum, Pantheon, and Roman Forum never cease to impress and are a must-see for anyone.

Many other historical, architectural and artistic treasures are scattered around the city. You can find some of them on the street in plain sight, others – in world-renowned museums and galleries like Borghese, MAXXI and Doria Pamphili to name a few.  

To round up your dolce vita experience remember to soak up some of the cultural scene. Eating out is one of Rome’s great pleasures.

Restaurants and open-air cafes line Rome’s numerous charming squares (piazzas). They offer plenty of opportunities to mingle with locals, or simply for people watching while enjoying local cuisine.

In Rome, no square seems to be complete without a fountain, each with its own artistic value and history. Trevi, Triton, La Barcaccia, the Four Rivers – the list of beautiful fountains (as well as squares) goes on and on. Legend has it that you can help your chances of returning to Rome by tossing a coin into the Trevi Fountain. 

When it comes to roaming connectivity, there is no need to toss coins at local mobile operator.

OneSimCard makes a convenient Europe sim card choice, as it offers low Data, Voice and SMS rates in Italy as well as many other European countries. You can also add a local phone number in Italy for even more authentic experience.  Multiple Discount data plans are available for your international SIM card.

If you have an eSIM capable device, you can download international eSIM straight from our website.

Strolling in Nice? Enjoy fast and affordable mobile service.

Many consider the city of Nice to be the capital of the French Riviera. From year-round sun and famous blue chairs to Art Deco architecture, museums and evolving restaurant scene, Nice, unlike its glitzier coastal rivals, has something to offer for every budget. The city is a popular destination for vacationers of all ages.

Castle Hill (Colline du Château) lets you enjoy a beautiful panorama of the Bay of Angels with the dramatic backdrop of deep blue waters of the Cote d’Azur. Fringed by the famous Promenade des Anglais it offers miles of the loveliest urban sea-front in Europe. Many events take place there including the annual Carnival and the Battle of Flowers. One can spend an entire vacation hanging out at the Prom (as the locals call it).

Museumgoers will enjoy the choice of over twenty museums and municipal galleries in addition to a large number of private contemporary art galleries and artists’ workshops. The most popular ones include the Museum of Modern & Contemporary Art, the Matisse and Chagall Museums.

Nice’s center is easily walkable. Enjoy the architecture of old city quarters, main square Place Massena, food and flower market Cours Saleya and the main shopping street Avenue Jean Medecin all within walking proximity. However, don’t fret if walking is not your thing – the city has a great public transport system or you can explore by bicycle.

Did You Know that Your travel SIM Can Power Hotspots?

Using OneSimCard for hotspot tethering
Using OneSimCard for hotspot data sharing

Very often we receive the question from customers asking if our travel SIM can be used in Hotspot devices and/or Smartphones to power the Mobile Hotspot feature. The answer is yes and yes!

What’s more is we allow you to share your connection with other devices at full speed for no extra charge. Many carriers throttle your connection when using the Mobile Hotspot on your smartphone and connecting other devices to it. These speeds can be as slow as 2G and 3G which virtually prevents streaming and many other apps like WhatsApp and Facetime from operating properly.

We never throttle your data. You can enable your Mobile Hotspot feature on your smartphone and allow all of the devices (think Tablet, Laptop, etc.) connected to the Hotspot to enjoy the same connection speed as your phone… up to full 4G LTE+.

Roaming in the Land of Fire and Ice: OneSimCard for Iceland.

  • Seljalandsfoss, Iceland

The Land of Fire and Ice is anything but ordinary. Technically a volcanic island, Iceland is famous for its unique landscape and stark beauty. Black volcanic rocks, glittering glaciers, erupting lava, bubbling hot springs, explosive geysers and many other natural wonders comprise numerous beautiful vistas.  

You can find something to do there year round, though summer is the most popular time to visit.  Warmer temperatures, less snow, more daylight and seasonal festivals draw the largest crowds. For most people the adventure begins after landing in the capital city of Reykjavík.

Reykjavík has a lot to offer including New Nordic cuisine, various museums and cultural sites.  You can even spot the Northern Lights from the city as well. However, many prefer to go out into more remote areas to enjoy Aurora Borealis without the interference of city lights, as well as explore other natural wonders the island has to offer.

Driving the Golden Circle is a popular day trip, especially for those short on time. The 186-mile route covers many natural landmarks including Þingvellir (Thingvellir) National Park with its tectonic fissures, Geysir and Strokkur geysers, as well as Gullfoss waterfall.

The Silfra Rift in a crack between the American and the Eurasian continents is one of the greatest dive sites on this planet. It boasts the world’s clearest waters with the visibility of 300+ feet.

For those with more time, the 828-mile Route 1 or the Ring Road around the island connects most of the inhabited parts of the country. Some of the most popular tourist attractions, such as the Seljalandsfoss and Skógafoss waterfalls, and Jökulsárlón glacier lagoon are also on or near the Ring Road.

Stay Connected

No matter how far your adventure takes you, having reliable means of communication is always a good idea. OneSimCard will provide you with all the connectivity you may need including Voice, SMS and Data with multiple Discount data plans in Iceland, throughout Europe and around the world. You can even add a local phone number in Iceland to your SIM card at any time.

Roaming in London? Bring OneSimCard.

London, England

Many parts of the U.K. have begun easing lockdown restrictions. Shops, salons, outdoor pubs and restaurants reopened in mid-April across much of the county. More public spaces should open over the next few months.

Country dependent quarantine requirements are still in place, so check government guidelines on what applies in your case. Although discouraged by the officials, traveling to the UK is already possible for many people.

The city of London needs no introduction. The capital city of Great Britain is world famous for its theaters, museums, parks and iconic landmarks including Big Ben, the Houses of Parliament, Trafalgar Square, Buckingham Palace and St. Paul’s Cathedral.

If visiting each and every venue is not your thing or not possible for other reasons, here is something to consider. London is a fantastic city for walking and cycling. Neighborhoods such as St. James’s, Mayfair, Knightsbridge, Kensington, Notting Hill and Covent Garden surround the visitor with great sights and sounds at every turn and on each corner.

The London weather in May is also quite comfortable with daytime average temperatures in the 50’s and the City will be a little less crowded then during the peak summer travel months.

How Does the Shut-Down of 2G & 3G Networks Around the World Affect Me?

Cell Tower. Photo by Vyacheslav Shatskiy

Many cellular networks are beginning to, or have already shut down their 2G and 3G networks. Cellular providers are modernizing their networks to 4G and now 5G, and need to use the radio frequencies used to transmit the slower, older 2G and 3G for these faster, newer networks. You can learn more about why networks shut down the older technologies on our IoT blog.

How does it affect your phone and SIM card connectivity?

As network operators around the globe begin to shut down (or “Sunset”) there 2G and 3G networks, your SIM and/or phone may stop working because they won’t operate on the modern networks.

It’s important to note that both a phone and a SIM card need to support the corrects bands for proper connectivity. For example, a SIM card that supports 4G will not work on a phone that only supports 2G and 3G bands and visa versa.

What does this mean for your service with OneSimCard?

OneSimCard eSIM, Universal, Expedition, or Europe SIM cards support all bands up to 4G LTE. As long as you have a 4G capable phone, they will operate as usual.

If you currently have a “Plus” or “Standard” SIM card, these SIM types can only be used for 2G and 3G service. To continue service, and keep your number, you will need to upgrade your SIM to one of the SIMs we offer, which support 4G and 4G LTE bands.
