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
iPhone XR, XS and newer
- Go to Settings, then Cellular.
- Select Add a plan, and the Camera app will open.
- Point your camera at the QR activation code until you see a message that says Installing cellular plan.
2021 Android and newer
- Go to Settings > Connections > SIM card manager
- Tap Add mobile plan
- Tap Add using QR code
- Scan the QR activation code
Activating eSIM on your Device using an Operator Notification
T-mobile, AT&T and some other operators make it even simpler to install eSIMs. They send a notification directly to your phone. Just tap on the notification and follow the instructions as in images below. 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#.

Purchasing was hassle free though cannot say the same about the service. It was patchy at times with a poor signal quality in Chicago. But can try it again.
Services Tsim –

I was told the card would be automatically activated on the travel date and I’ve landed in the USA with no network and no activation. This is highly unprofessional. The call center guys are quite unresponsive as well. Order number 41942

Shashank Tambe –
The sim worked well with my phone, though the TSIM operator could not confirm my phone model. But my model is 4G compatible, here in India, and it worked withe US mobile as well. Only condition is I had selected T-mobile as my operator.
The data may disappear suddenly for some time, but need not be big issue. In US you will get free wifi almost all malls or big / small restaurants, with “no clause attached”. Indian airport has free wifi, but only for 30 mins and you need to put your mobile number, but not like in US. I was in SFO (CA), and network works well most places. If you have take your Indian sim on international roaming, cost would be same as TSIM, or little more but with TSIM, you have liberty to provide your number to any establishment. so it is helpful.
My mobile usage was very limited but I used data to find locations, then call uber, and so on. You will feel safe with the sim card in your mobile.
Ram –
Excellent. Works as advertised. Using it for 4 weeks and I recommend this Sim for all US visitors. Getting a Sim here in US is expensive and data usage rates are prohibitive. Lastly the most useful feature, unlimited calls to India keeps me in touch with home everyday.
If you are visiting California, make sure you have a 4G phone. 3G phone will not connect to the network. Not mentioned on Tsim web site, but useful if mentioned.
Other states in US, I am not sure.

Services Tsim –
Thank you for your kind words and tips. Its true that 2G and 3G networks are being phased out, and coverage is progressively reducing. It is therefore best to travel with a 4G phone as you have suggested.
Services Tsim –
Thank you for your detailed review.
Anil Bhasin –
I bought a 2 months validity T Sim connection for USA . To my dismay, my phone does not work where I am i.e. at Glastonbury, Hartford, CT. It does work erratically in some areas only. It is already 22 days since I arrived in the US. My best efforts with the company has borne no results. I recommend anybody buying this connection to make sure that T Mobile, which is T SIMs service provider in US works in that area before going in for this. I am told T Mobile has very poor connectivity in most areas of US. It has been a complete money loss for me.
Services Tsim –
As we had specified via “Check my Phone”, the phone model you were carrying was not compatible with 4G networks in the US, and will have just 50% coverage for 3G. We recommend to carry a new model of phone for international travel, since networks abroad use new technologies more intensively. We apologise for the inconvenience caused.
Praveen Kharbanda –
Excellent SIM card and the response of the staff was fantastic.
I really enjoyed our trip to the US because we were always without any tension of communication hassles.
Will recommend for all

Ankit Sharma –
Didn’t get 4G in whole SFO but calling and 3G was fine. One horrible thing was T-SiM gave some used old number to me and I used to get day night wrong number calls and shameless T-Sim didn’t apologize also for this mistake. You can buy this SIM bcoz India call is free but always be ready to except wrong numbers
Services Tsim –
Our supplying partners do reclaim old numbers that sometimes cause this problem. We apologise for the inconvenience caused to you.
