Frequently Asked Questions
Does a Sao Tome and Principe eSIM come with a phone number?
Most travel eSIMs, including most Sao Tome and Principe plans, are data-only and have no local number. You keep your usual number on your main SIM for calls, texts and WhatsApp. Plans that include a number or minutes say so on the plan page.
Will my phone work with a Sao Tome and Principe eSIM?
Yes, if it supports eSIM and is not locked to a carrier. To check, dial *#06#: if an EID number appears, your phone supports eSIM. Most iPhones from the XS/XR on, Galaxy S20 and later and Pixel 3 and later do, except most models sold in mainland China and some sold in Hong Kong and Macao.
Can I keep my own SIM and WhatsApp while using a Sao Tome and Principe eSIM?
Yes. Your eSIM and your main SIM can be active at the same time. Use the eSIM for mobile data with data roaming on for that line, and turn data roaming off on your home SIM to avoid charges. WhatsApp keeps working on your usual number.

"Having 365-day packages is very good for me, I am a cabin crew member and I use it without any problems wherever I go. Sometimes it even works in places that are not on the list. I am very satisfied and will renew my package when it expires."

In Turkey and Georgia in the summer of 2025, I used the app, and everything worked perfectly! The prices are cheaper than buying a SIM card at the airport.

During my 5-day trip to Greece, my wife and I shared the "Europa special 10 GB" package. We used it extensively and without interruption in all 5 days, but only managed to use 5 GB. If I ever travel abroad again, I will definitely choose Mobimatter.

I highly recommend using MobiMatter’s eSIM! I had some problems activating it and couldn’t figure it out on my own, but the MobiMatter team helped me very quickly and explained everything clearly and in detail. Thanks a lot to their support, I was able to activate it and get connected. Great customer service! 😊
