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

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#.

Tanmay Bhagwat –
Was good enough, though I couldn’t use data for some reason, so had to rely on wifi to get by. Network was a bit patchy, but would recommend!
Services TSIM –
Thank you for your balanced review and recommendation.
Pankaj Maheshwari –
I have been using TSIM for USA on various visits and have found its working very satisfactory. It is very reasonable in comparison to other available options and offers various combinations to suit your requirements.
Services Tsim –
Thank you for your kind words.
Tyakal Venkataramana –
This was reasonably priced and very useful for travel in the US. It worked very well on my mobile. In all, I rate the service very highly.
Debendra Modi –
Bought for 2 months – Did not work in the second month.
Even after one full day without phone, they were still checking.
They have said a new SIM with a different phone number will be sent and received in 3 to 4 days – 3 to 4 days without phone and a new phone number. No tracking number provided. Not sure if it has been really sent – Will know if received in 3 to 4 days.
Not willing to overnight the SIM as they do not want to spend.
Worst Service.
Services Tsim –
We are sorry your SIM card stopped working during your trip. We have sent a new one in expedited mode, but do not have an overnight option to your zip code. Thank you for recording your experience.
Avinash Hirekerur –
Used for USA trip in August. Very prompt and fast service. Very competitively priced. I was clearly told that my current mobile is not compatible. However I purchased anyway as I had planned to buy a new one there. The old mobile worked for SMS and calls but not for data. After moving SIM to new mobile, everything worked fine. So I apprecite their knowledge and upfront communication.
T-mobile coverage was as expected.
Overall I am very happy with the support, speed and communication of customer service. Looking forward to trying e-SIM for the next trip!
Services Tsim –
Thank you for your balanced review. We will investigate why you had Data connection issues.
Services Tsim –
Thank you for your kind words. We are actively looking for more eSIM options and hope to have them ready by your next trip.
shyam kumar bhagwat –
I used it in Chicago and california.
teh calls were OK, still intermittent network issues, but the data was more problematic as it did not connect most of the time
Alka Tuteja –
This was second time I purchased TSIM for travel. Decision was driven by the fact the purchase not only gave me better value for money. There were no coverage issues as I could find out the service provider details from the TSIM website and check the network availability from the service provider’s website site for my destination. This is very much like my previous travel SIM purchases, where I discovered the network or lack of it on the arrival at my destination.
Purchase experience was also good, SIM go delivered in less than 24 hours after placing the order.
Services Tsim –
Thank you for your detailed review and kind words.
Mahavir Jindal –
SIM was delivered on time along with the free adapter. Was very skeptical as i had not heard of this company but was pleasantly surprised with the experience. Worked flawlessley.
Partsof US where Tmobile did not ave great coverage,this sim couldnt help either. Some recommendations:
1. Clearly state that the speed would be 4G and not 5G
2.Refresh the wesite. While functional, it does not inspire trust.
Services Tsim –
Thank you for your kind review and suggestions. We take all suggestions very seriously and will work on implementing the same.

I had lot of fear connecting my family after reaching USA first time for studies. But TSIM solved all my fear. I could connect to my family seamlessly in both voice and data calls unlimited time. Also it is very cost effective for students like me and the price beats local mobile plans. It worked all the time. Thanks TSIM team.

Ashish –
I used the TSIM USA SIM (12 GB pack) during my week long stay in Denver. The internet speed was excellent and coverage was good wherever I went. But, if you are going to use the SIM for accessing the maps, checking the emails, WhatsApp, etc., then I recommend 6 GB pack for week long stay. The Free WiFi service is present In most of the public places.
Vinay Rajaram Patil –
