Coverage
Our cheaper SIM cards work on the T mobile network, either directly or through their partners. T mobile is an ultra fast network, however its remote area coverage lags that of AT&T. If you intend to visit many remote areas in the USA, such as Alaska, natural beauty spots, national parks etc, you may want to consider our SIM cards that use the AT&T network, marked (High Coverage).
Receiving calls
People in USA can dial your number directly to reach you, for example, 1 804 555 1233; People outside USA need to add + to your number, for example, +1 804 555 1233
Calling a number in North America
Dial the 11 digit number directly; for example, call number 1 804 555 1233 directly. You can also add + to the number before dialing. There is no distinction between a landline number and a mobile number in North America
Calling India using Direct Dial
Dial “011” or “+” + country code + phone number. For example, to call India number 022 24216344, dial “01191 22 24216344” or +91 22 24216344.
Calling India using 2 stage dialing (for High Coverage cards):
Dial USA Access Number +13476701779 & when prompted dial the India number in full international format. E.g. 912224216344).

What is an eSIM?
eSIM stands for “embedded” SIM which is installed in your phone by scanning a QR code or tapping a notification. If an activation date is required the QR code / Notification is sent after activation, else 24hours after completing your documentation.
eSIM Advantages
- Easy to use: Set up your plan by scanning a simple QR code or tapping a notification.
- Save on Shipping cost: No physical delivery requirement
- Save on time: In a rush to travel? We will send eSIM QR Code via email. Scan it as per instructions and It will be ready to use upon arrival.
- Keep your original SIM: The eSIM is in addition to your original SIM which will work as usual if you need it.
eSIM Disadvantages
- Unfamiliar: Since it is a new technology expect to be learning a bit.
- eSIM Compatible Phones: eSIM will only work in eSIM compatible phones. As a general rule, iPhone 11 and Android model 2021 and higher models are compatible with eSIM.
- Single Use Only: Most eSIM codes can be used only once. Please do not delete the eSIM created on your phone, since it cannot be recreated on your phone or any other phone. However you can de-activate the eSIM when not needed from your settings.
- Transfer of eSIM: To transfer an eSIM from one phone to another you must visit the store of the Operator concerned. However some USA eSIMs can be transferred from one iPhone to another.
Activating eSIM on your Device using a QR Code
Most eSIMs are installed using a QR code. The QR code is sent to you by eMail. You need an Internet connection to install an eSIM

Activating eSIM on your Device using an Operator Notification

The notification is sent to the phone you intend to use on your trip for which you have given us the EID and IMEI number by dialing *#06#.

Thank you for your kind words and understanding. Some phone models are confusing, esp those that have variants for each country. We are using this case as an example to improve our phone recommendations.

Very Nice Service and quick support from TSIM customer care.
I travelled to East Coast as well as West Coast cities the network for the sim was available evrywhere. Also the calls to india were totally free and voice quality was also good. Highly recommend this sim if you are travelling to USA.
Thank You Tsim for kind suport and service. I will again use the same for my next international trip.

I really liked TSIM. The coverage was really good in Portland, Oregon & data speed was superb. It simply worked like a charm. I would definitely recommend this to my friends.
One problem I observed was with the customer support. While buying the SIM, the customer support told me that my phone is not compatible with the bands in US while it clearly was as per the phone specs. The customer support needs to be more diligent towards the claims they make.

I would really recommend T-sim for everyone travelling abroad. It worked great for US (for others also I guess it would be good). My review would be related to US. You may hear from people that USA sim cards in India are really expensive and you should buy the sim card after you travel to US but believe me I had a great experience with T-sim. It was much cheaper than any of US sims sold in India and even cheaper compared to US. I would really recommend this product, it would be great for your US stay. And also customer care from T-sim is really responsive. I appreciate that.

After initial hick ups of starting up it has worked wonderfully well. Would highly recommend as after sales service was also prompt and very satisfactory. Worked in sfo and LA. Free calling to India is a huge advantage.

We are sorry you did not like this card as much as the previous one. Thank you for taking the time to provide details to our representative.

H20 wireless for USA was the worst card I have ever used.
Dipankar Mukherjee –
Very good service . I am using it in Alpharetta, Atlanta with no problem. I heartily recommend it. Their delivery of sim , the mobile number sending through e mail, activation in right time are praiseworthy.
bdpk3 –
Good Network (voice) , but net speed slow may be because phone is not compatible. TSIM should publish a list of low cost budget phones compatible for US network.
Please a suggest few such models(Android phones) so that I plan for next trip.
Overall, satisfied with TSIM which comparatively cheaper than other competitors.
Sadan Shenoi –
Worked lawlessly in Atlanta GA. Could not us data as my phone was not compatible. Very satisfied.
PM –
The SIM did not work well. Even though i was in LA in USA multiple times network was not there. I bought two SIMs and both have same issue of no network.
What i did not like is the customer care service of TSIM, they are very rude and even started sharing their frustration that they have to work on Sunday which has nothing to do with customer. At last, i have to connect with supervisor but after long struggle with customer service person. Not at all professional in their service.

I have used 8 GB High Coverage ( H2O / ATT sim ) plan from 17th may to 7th June 2018.
I had been appraised by TSim team that 3G will only work for MI 5 phone, before I started my journey..
To my surprise, I almost got 4G coverage in metro areas…Free calling within USA and to India makes use of product hassle free.. No need about charges..that makes whole journey hassle free…
I was very satisfied with service and product… I will use it again for my next trip.

jayantbiswas –
Very good service at the price. I used the SIM for a month while travelling in the US west coast cities and got good coverage via AT&T for local as well as India calls and also data. However my SIM was supposed to be valid till 01 June and I was able to make local calls on that day and got data also.; but India calls were not allowed that day and I kept getting the message that my balance was nil.
