Best US SIM Only deals for Travelling in America in 2023

Finally out of lockdowns and ready for your next working holiday or family trip to the USA? Can’t contain your excitement? Neither can we!

Planning for a USA trip can be hectic and tricky at times, not to mention the hefty roaming fees imposed by local telcos. However, getting prepped-up before you board your flight may just be what you need to make your travel journey smooth and hiccup-free!

Getting a local USA sim card surely would have crossed your mind if you’re travelling any time soon, so you can enjoy the benefits of being connected as soon as you land without worrying about roaming costs! Here’s a rundown of frequently asked questions and the variations in USA sim cards that you can plug into your smartphone and avoid international roaming charges.

What is a Prepaid US sim card?

A prepaid US sim card is a pay as you go sim card that you can insert into your UK mobile phone for the United States, so they'll work in the US and possibly Canada or Mexico. If they're US-based SIM cards from US carriers such as T-Mobile or AT&T like the ones we sell at SimCorner, they'll get assigned a USA phone number. If they're not US-based SIM cards, they might be roaming sim cards. They will still work in the USA but be assigned another number, such as a UK number or Estonian number, etc. 

The best USA Sim are the local sim card options. As they already include unlimited calls, unlimited SMS, and data allowance, and usually get better coverage and data speeds.

Also with Prepaid USA SIM only deals, you do not sign up to a contract, as they are pay as you go options. The USA Sim only deals we sell at SimCorner are all 30 day SIM options that come with set features that last 30 days. This means no hidden fees or charges.

Will my phone work in the US?

Most UK citizens flying to the States should remember that network providers in the US use different frequencies to those back home. If you want to use your phone over there, you'll need to double-check what frequencies it supports before deciding to purchase a sim card for USA. You can go to a mobile phone shop, or you can use the contact us link above to get in touch with us, and we would be able to check if your phone is compatible with the prepaid sim cards from Verizon, T-Mobile or AT&T.

You will also need to make sure your phone is unlocked. If your phone is on a post-paid plan or contract with your local carrier it doesn't mean your phone is locked. But if you are unsure, please check with your current service provider.

Choosing the best USA Sim Card

How do you pick the prepaid USA sim card for your travel needs? The first step should be checking who the carrier is for the prepaid sim you are about to purchase. In the USA, there are 3 big carriers: Verizon, AT&T, and T-Mobile.

T-Mobile - One of the most competitive cell phone carriers in the US, T-Mobile is an excellent choice for picking cheaper SIM options with good coverage across the vast amount of mainland America and Hawaii. They also offer the best prepaid sim bundles that are great value for money.

Verizon - America's best carrier for coverage is Verizon, which provides excellent coverage and fast data plans. Verizon's 4G LTE network currently has the best nationwide coverage in USA compared to any local carrier, which is great if you are driving around town.

AT&T -The last big mobile carrier, AT&T is a popular choice as it offers the most coverage across the USA and its territories. But recently, Android phones not purchased directly from AT&T, are having calling issues on the AT&T network (data is working fine). If you need calling service we recommend that you purchase the T-Mobile or Verizon, otherwise you will run into issues whilst over there.

Similar to here in UK, the US also offers a range of smaller phone carriers such as LycaMobile or Lebara. While these are still local sim cards, these run on one of the main phone networks noted above but offer their own services. These include Metro and Ultra, which both run on the T-Mobile network.

Although these smaller phone providers use T-Mobile's network, they have some limitations in order to reduce prices. They may not span the whole network, and coverage may be limited in many places. This would mean you would not get the best coverage, as compared to other country-specific sim cards. In addition, Metro also has strict limitations on video streaming in its data.

This is why we recommend choosing a sim card from one of the two main carriers in America when buying USA sim cards, as they offer coverage in most of the main cities and/or tourist areas.
