This is a pure scam
This is a pure scam, they send a QR code to your phone!! How do you scan a code already on your phone!! Stay away from this company. The issue I have is it does not recommend checking if your phone/device is compatible with an e-sim before you pay!!
Response from MobileSIMJun 8, 2026
Dear Patrick, We are very sorry for the inconveniences you had with our service. Please note that not all devices are eSIM-compatible, so it’s a good idea to check that your device supports eSIMs before getting started. Please follow the link below to check if your device supports eSIM. https://MobileSIM.com/how-to-use#device-compatibility If you want us to check this for you, please provide us with the IMEI number of your device. You can find it by dialing *#06# on your device. Also, note that you might not even notice that the eSIM is already installed after scanning the QR code, and that is because the eSIM will most likely be assigned a random name such as: "Travel eSIM", "Business", "Cellular Data", "Personal" or probably a different one. IMPORTANT NOTE: To download the Travel eSIM to your device you need a stable internet connection, preferably a WiFi connection. Once you start installing your Travel eSIM, do not interrupt the installation process or your Travel eSIM may not be retrievable. If you need extra assistance, we're here 24/7.

Tried MobileSIM in Mauritius, but too weak signals during daytime.
Tried MobileSIM eSIM in Mauritius. 1 GB over 8 days option. After 330MB usage it became very weak or nonexistent, especially during daytime (when I needed it the most!) There is some useful data connection during night time. This is probably a bandwidth issue from the local mobile partners of this company.
Response from MobileSIMNov 12, 2025
Dear customer, We appreciate you sharing your experience with our eSIM in Mauritius. We are sorry to hear the data connection was unreliable. We are currently investigating potential bandwidth issue with our local partners to improve our service. We appreciate your patience and understanding!

The eSIM from MobileSIM for Namibia does not work at all. The custom support was not helpful. The trouble shooting e-mail often repeated the same content. After several communication, we had to give up. Updated per Nov 18. I got the refund from MobileSIM. That is good. However, my husband who had the same issue and requested the refund. He did not get response from MobileSIM so far

Hello, and thank you for your feedback. Resolving an eSIM connection issue involves several verification steps, which may sometimes feel repetitive. Our Support Team will contact you shortly to provide further assistance. Thank you for your patience!
