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.

- Tap Add mobile plan

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#.

Using the 4G Sim in Texas. .No Network breakage at all. Works amazingly well while connecting to VPN’s too. The good part is they have a Whatsapp number to answer all the queries 🙂 Kudos team. .!!!
Anil Gutta –
These Guys are Fraud. They have sold the SIM and it did not work when i was in US.
They came back saying it is for fixed duration even if i have not used the SIM. They should tell us upfront why their SIM does not work in US .
I lost my money on this company and would not recommend to anyone to buy their Products.
Services Tsim –
The validity of the SIM card cannot be altered once it is activated. We are unable to detect compatibility of your phone due to lack of details. We request our customers to select “check my phone” option before travel to avoid such situations. We apologise for the inconvenience.

Used Tsim/Lyka Mobile in Massachusetts, Connecticut, Washington DC, and Virginia on my 3G phone in November 2018. Had great coverage for voice calls as well as the internet! India based Customer care is exceptional with excellent, immediate response and helpful, knowledgeable staff! Thank you, Tsim 🙂

Worked only in few areas!

There was verbal confusion with the model of phone you have used. Our tele-agent heard One Plus 6, which is compatible with USA networks, whereas you seem to have used One Plus X, which is not. We apologise for the inconvenience, and request our customers to use the check-my-phone form on the product page while placing the order to avoid such confusion. Thank you for taking the time to record your experience.

I had purchased the USA unlimited H2O Sim from TSIM for my 3 week US trip. There service was exceedingly superior and the coverage was exceptional. i had been to three national parks in the US and travelled extensively by road. The data provided 4gb was great as i was totally dependent on the navigation almost all the time.
Would highly recommend TSIM’s USA unlimited calls and 4GB sim for anywhere is the USA. I have tested its performance in New York, east coast. Grand canyon area, Vegas and California on west coast. The signals and data speeds were more than satisfactory.
Services Tsim –
Thank you for your kind words and for detailing where the high coverage SIM card worked.

Thank you for your kind words and for confirming the cities in which it worked.
mankala –
I used the sim in Chicago, milwaukee, phoenix, las vegas, sfo bay area, texas, baltimore areas. Everywhere both 4g and calls worked excellent. Ordering process and customer support have been fantastic in guiding with handset and ensuring plan and is understood properly. Only problem I had was calling from marketing companies in US. I guess that is common with all such cards.

I purchased High Coverage 4 GB data sim card for USA travel. In USA, I visited Washington DC, Niagara Falls, New York and California. Ultra fast 4G/LTE data and easy-to-place local calls (withing USA). In total, I found the sim card very useful. Here is my review:
Pros:
1. Very easy to select and place order online.
2. Reasonably cheap in price in comparison to Airport vendors.
3. Door-step ultra fast delivery .
4. Pr-activated sim available.
5. Know your mobile number in advance.
4. Fast data and wide network coverage.
Cons:
1. On arrival to USA you need to install profile (needs WiFi, that is freely available at the airports).
2.India calling does not work properly. I got H20 network, and they have provided an international access code. First I need to call on that number and through that to Manually my India’s numbers.
3. Always need to dial my India’s number.
4. These is lag/non-clear voice in India calling from most parts of the USA.
Overall a nice experience. In future I might purchase it again for my overseas travel. Thanks
Services Tsim –
We are sorry your experience was not as good as we had hoped. Thank you for your balanced review.
Subeh Sharma –
Used it for 10 days in bay area USA and it worked without any issues. Only problem was there was no way of checking how much data balance is limited so had a tought time as tsim support team also couldn’t find this out. Apart from that coverage and data wise it worked like a normal sim should.
Services Tsim –
Thank you for your kind words and review. Unfortunately this SIM card operator gives no easy way to find data balance. We apologise for the inconvenience.
