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

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#.

Good sim.worked from the minute I landed in USA. Though at times no range, mostly worked great. Gave us the needed confidence and coul do all travel bookings well. Happy feeling is end result. Could remain in touch with India all the time in US.

Thank you for your kind words
Subodh P Yeotikar –
Used TSIM during recent visit to USA(April 2017). Worked very well during entire trip. Even Data downloading speed was good. Good to have found a cost effective solution.
Sunil B –
Very good network coverage in California and New York
Services Tsim –
Thank you for your kind words and recommendation.
Mahadev Desai –
Excellent coverage and ease of use in California / Las vegas during my recent visit to USA. Strongly recommended. Only down side for people staying for more than 30 days, (but say 35 to 40 days), one has to recharge for one month only.
RG –
Used it in Boston. Worked fine, except signal loss in some tight nooks and corners within few buildings. Connectivity to Indian as well as local numbers was excellent. Recommended.

Krishnan Dharan –
As mentioned in other reviews and TSIM’s description of product, the coverage is provided by [T Mobile], which does not have as wide a network in the US as AT&T or Verizon, but for us it worked in most places along the East coast for outgoing calls. For incoming calls, most of times it went directly to voicemail for some reason. Still, I think it is an acceptable product and good value for money.
Services Tsim –
Thank you for your kind words and detailed review.
Feroz Khan Pathan –
Worked good only for some set of indian phone number. This is strange and I reported this many time but they were always saying we will get back to you but no one called back.
The issue was i was able to call only some set of numbers which I already called in first week but from second week onwards when I tried calling some other indian numbers I was not able to.
And calling there customer care did not help either.
Rajesh Kumar –
In SFO (USA)… network was very poor and unable to use it.. I felt waste of money..
Services Tsim –
We are sorry for the inconvenience. As informed to you, Samsung J7 SMJ700F does not work with most USA carrier frequencies. Please do select “check my phone” while ordering your SIM card, and ensure that you travel with the phone you have informed us about. Thanks for your review.
Services Tsim –
We are sorry for the inconvenience faced by you. Thank you for taking the time to review the product.

Apart from bad customer care experience, I recommend this.
And also faced some technical glitches but had a pretty good coverage (not 4g all the time) in most of region.

Prashant Dhar –
I have used TSIM services twice now..both in Los Angeles area and am happy with the services.
Especially the last time when I was given [T mobile] sim I think the coverage and reception were great.
I would recommend TSIM as its great value for money
Services Tsim –
Thank you for your kind words and recomendation
Services Tsim –
Thank you for your recommendation. We are sorry about your poor customer care experience. We will work to ensure it does not happen again.
Geo Antony –
This SIM card was extremely useful and we had complete coverage everywhere we went especially in the north east of US covering New York and New Jersey. We found the 4g data very useful navigating our way through New York city on foot.
Services Tsim –
Thank you for your kind words and information
Sanjay Pujar –
I bought a simple mobile card. T-sim promised me 8gb data and also 8gb was written on my card but I could use only upto 4gb. Even after repeatedly calling and e-mailing T-sim, I have received no call back or mail from them. Also simple mobile has bad coverage in sub-urban areas.
Services Tsim –
We had spoken to the SIMPLE Mobile Customer care on receipt of your complaint. They had confirmed that you had 8GB of high speed data & had used just 5.21GB. We had forwarded the following response to you:
“Hello
We can confirm that your SIM has been allotted 8GB of high speed data. As of now you have not exceeded the limit & hence the speed is not reduced due to exhaustion of data limit.
Lack of data speed can also be affected by many other factors like (not limiting to) location, network coverage etc. If you have any further questions or concerns, please contact one of Simple Mobile Customer Care representatives at 1-877-878-7908 or visit http://www.simplemobile.com“

Abhey –
Visited USA in March 2017 and took this card in Advance. This is much cheaper than those offered by Famous Big Branded Operators like Matrix and the ones offered at Airport Kiosk by Uniconnect. Service and Support by T-SIM was great , but T-Mobile Operator of USA offers very poor coverage , better opt for Plans of Other operators.
Services Tsim –
Thank you for your kind words and recommendations.
Arudra –
I visited New Orleans (Louisiana) and Des Moines (Iowa). I did not get any network problems anywhere including my work location which is located at outskirts of Des Moines. Call clarity was extremely good. Cost wise it is very cheap. I already recommended to few of my colleagues. I will certainly use Tsim next time I visit any foreign country.
Nitin –
Worked very well in USA in California. I recommend this and will use this again.
Atul Awate –
Only the dialing is working properly. Data is on 2g speeds in the Bay Area. Tech support, which you are lucky if you can get hold of them, gives the same standard answer.
Services Tsim –
Thank you for your review. As informed to you by email, it is best to select “Check my phone” option while ordering. This will let our helpdesk check compatibility of your phone with 4G frequencies used by various carriers in the USA. In your case the phone was not compatible with any operator in the USA for 4G frequencies, hence it used 2G. We apologise for the inconvenience caused.
Chirantan –
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 my number with my credit cards.
It is lot cheaper than those available at airport. (~30% cheaper)
