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.

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#. Click here to know why IMEI and EID numbers are needed.

I didn’t get signal at a lot of place. But when I did get signal, it worked just fine. 4G internet also worked very well when there was signal.
Services Tsim –
The phone you purchased for the trip was not compatible with USA carrier frequencies for 4G. It is best to select “check my phone” option so that our helpdesk can support you in phone selection. We are sorry for the inconvenience caused. Thank you for your review.
Kavita Bothra –
I took a TSIM and had a very bad experience. It worked only in New York but only in patches. Then, Chicago and Indianapolis and Seattle had negligible or nil service. Las Vegas nil service.
And in SFO it was very patchy.
The data connection was very poor.
I’ve used TSIM for Europe and was happy with their services but US service was a total failure. Not recommended.
Arun B –
Travelled to West Coast, Chicago and East Coast in May 2017.Very poor data signal even in Cities like SFO, LA, and NYC, voice is OK.. My phone has Band 4 and Band 2 reception. Never got 4G signals anywhere. Waste of money. In the US only AT&T is dependable, best to avoid T- Mobile

Besides phone call service, sim card of TSIM is very good so far as speed of internet & other services like Whatsapp are concerned. It is indeed pleasure in using the sim card!
Services Tsim –
Thank you for your kind words.
Dr. Debanik Roy –
Very good service from TSIM and the USA SIM card is simply excellent! The voice quality was clear without any breakage / discontinuity. With unlimited phone calls to USA & India, the service is no doubt worthy of purchasing. I will certainly recommend the SIM card of TSIM to all my relatives, friends & colleagues. It is “value for money”!! I wish TSIM to emerge as a big player in global sim card service market in near future.
Anagha –
This is a very nice mobile service sim for short period of traveling. I had purchased this for my USA trip of 10 days and could use it like my local mobile service. Unlimited phone calls to local and India both, incoming and outgoing. Also it was very useful whenever I wanted to place an order or book a taxi as people there were expecting local US number for booking. Network range is also amazing, never got disconnected or found area where service is not working unless its a restricted area. Data connectivity is also good as I had opted for cheapest(1 GB) sim card and my handset was supporting 2G. But still I was able to use GoogleMap and Whatsapp precisely. Overall very good option to have this sim for short period of time and its very cheap compare to other services in USA. And best part of it is, it gets delivered to home in India and can be activated before travel dates as per our requirements, unlike other sims which needs to be purchased after arrival on airport or local telecom shops. This is the Best option anyone can try. Good work team TSim snd keep it up. Very much appreciated the service.
Regards,
Vrinda(Anagha)
Sunil Patil –
Recently I am using the USA prepaid card for 30 days. When I traveled to Rapid city & mount Rushmore, I got range of AT&T but was not able to use data for complete stay of 3 days. I tried every thing but it did not work on my i phone. Once I came back to Minneapolis, i got range of [T mobile] and data started working. I do not know the reason, but surely it seems that there must be some hidden condition of data usage whenever there is no range of [T mobile]. It means that data usage is restricted in case of other service provider. Surely I am not happy and worried that it will happen everywhere there is no range of [T mobile].
Services Tsim –
T Mobile network is strongest in urban areas. For trips to far flung areas and national parks we recommend the AT&T option, currently provided by us through their partner H2O. Please select “Highest Coverage” in the option drop down for this. We apologise for the inconvenience caused. Thank you for your review
Setu Shah –
I have purchased it and got it in 2 days in Pune – it was having an amazing call & data service as I have purchased 10 GB data sim……much much better than matrix cellular services……Amazing service of TSIM’s product and extremely happy with their overall service right from ordering till usage in the USA……kudos to TSIM and keep doing the same will make you industry player in this segment………

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.

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.

Apart from bad customer care experience, I recommend this.

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

Thank you for your recommendation. We are sorry about your poor customer care experience. We will work to ensure it does not happen again.

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.

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“

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.

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)
