I held off on the

I held off on the review u til I got to USA to check it would work. Right now im sitting on a Big Bus open top tour bus in Miami. It works a treat, called home to the wife on whatsapp and videocalled the family. Brilliant really happy

Worked great for my trip

Worked great for my trip to LA - I did notice I was on 4G the whole time despite having a 5G phone but the speeds were sufficient to make whatsapp calls home and to use sat nav in the hire car. . . . . . there were a few steps to be done while still in the UK that were unexpected when purchasing but the steps were clear and it was easy to do.

Always great service and support.

Always great service and support. SimCorner is the best overseas SIM provider. Bought 4x Cards for our group family Vacation and SimCorner made it so easy to register and activate as soon as we landed in the USA.

Having used a different company

Having used a different company for a USA SIM on previous travels, which did not work at all and the customer service was a disaster, I can not be more happy with SIMCORNER. Customer Service was exceptional, I actually felt like a customer and not a number. Was able to get my phone numbers early so I could update my contact details before leaving, which was important to me. All other questions were answered fast and comprehensive. The actual phone service was flawless, not once let me down for voice or data. I can only recommend this company and SIM package.

What will my phone number be?

Upon arriving in either the USA, Canada or Mexico and after inserting the sim card in your mobile phone, you can go into your phone settings menu to view your USA phone number. You will also receive a text message from TMobile noting your local USA phone number.

Can I get my phone number earlier?

When a sim is activated we are able to retrieve the phone number from the system. As an option, if you are travelling for less than 30 days you can look at providing an earlier arrival date when purchasing the sim card, bearing in mind that your 30 days of service will still begin from that date. You can then e-mail us on the activation date you provided requesting your phone number which we can then forward to you.

How do I check my Data Balance/Allowances?

To check your data balance you have used, you simply need to dial #932#. A prompt will show how much data you have used so far.

If you receive any prompt/text messages noting that you have zero credit balance then you can ignore as it does not relate to your data balance.

You simply need to have both MOBILE DATA and DATA ROAMING ;functions ENABLED/TURNED ON in your phone to use the service. The SIM will be active from the activation date you have provided. It is on this date that your 30 days of service will automatically commence.

What happens if I am travelling for longer than 30 Days?

This sim cannot be recharged. If you are travelling for longer than 30 days, please purchase multiple eSIMs accordingly. For example, if you are travelling for 56 days and are departing on the 1st of September, then you should select '2' for the quantity (qty) and add them to the cart. Then in the cart page enter the activation date for the first sim as 1st September and then press the "+" to enter the activation date for second sim as 30th September (you can select whatever activation date you like or even have them overlap, just keep in mind that your 30 days will begin from that date). You can then use the two sims for 30 days from the dates you have provided. (Please note: each sim card will have a different phone number).

As long as you are aware your 30 days will begin from the activation date you provide for each sim, it's up to you what date you provide ensuring it covers you for your duration. It's fine to have services overlap.
