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.

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

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#.

SHILPA PARULEKAR –
For the cost, I could have said 4 stars, but it doesn’t work at all in areas of Frederick, Hagerstown, etc. Working very well in Washington. Too many call drops and very weak signal outside of Washington in Maryland
Services Tsim –
Thank you for your kind words and for confirming the areas in which the SIM card worked. For remote areas and national parks we suggest use of the SIM card marked “best coverage”.
Services Tsim –
Thank you for your review and for confirming its performance in specific areas. We are sorry it did not work for you in the outskirts of Washington.
Vivek –
Very good pre-sales service and prompt delivery.
Good coverage in San Francisco and the Bay area.
Needs improvement in coverage in ‘remote’ area like Grand Canyon, Zion National Park.
Yatin –
connections are present at most places but the signal keeps on fluctuating that is keeping going and coming at all places causes lot of troubles.It also sucks a lot of battery and hence phone has to be kept in airplane mode in all the time when not in use.Net speed is decent but only when the connection are proper.
Services Tsim –
4G does consume more battery as you have rightly observed, esp when you are traveling from place to place. However this may not be a problem specific to the SIM card you had taken. Thank you for taking the time to review the product.

Excellent network coverage in USA. I was getting good speed on LTE. After ordering, I got my sim in one working day. Apart from some technical glitches which did not allow me to know my number until few hours before travel, the sim worked smoothly. I was required to update the APN settings

Used my TSIM sim card since arrival US nearly a month back. No problem in connectivity even in remote locations and small towns.
Reasonably priced and Great value for money.
Services Tsim –
Thank you for your kind words and review.
Nirav Vador –
Worked perfect for my short stay in the USA. Coverage in Texas was excellent and up to the mark whenever required. This came in very handy as it was active the moment I landed in the USA. Service in SFO was a little patchy, but that was probably because of the network connectivity issue where I stayed. I would recommend this to all.
Services Tsim –
Thank you for your kind words and review.

Mahima Unnikrishnan –
Bought TSIM for my 3-month stay in Illinois. Worked okay, product was as expected.
Cons: The coverage was poor sometimes while travelling via road and also at times, messages were not delivered/received on time. I visited Wisconsin,Madison once and the network coverage was especially poor there.
Otherwise, it functioned well for the most part. Unlimited voice calls to India for the entire period was a definite bonus.Would consider purchasing again if I return to the US.
H N Muralidhara –
Value for the money!!
It made my trip super easy and memorable. T-SIM started working as soon as i landed in USA.
The coverage was really good in most of the US Cities. In most of the tourist attraction places, we will get free Wi-FI connection.
Overall excellent services from TSIM team.
Regards – Muralidhara
Services Tsim –
Thank you for your kind words.
Services Tsim –
Thank you for your detailed review and continued confidence. For better coverage on road between cities we recommend an AT&T based card (marked “best coverage”).
