The Samsung Galaxy Z Fold4 smartphone is equipped with an eSIM.
Thanks to the eSIM, you will be able to use dual SIM cards. It means that the eSIM on Galaxy Z Fold 4allows you to immediately connect to another mobile operator without using a physical SIM card.

Ubigi is one of the carriers that support eSIM for the Samsung Galaxy Z Fold 4, in about 190 destinations, on the 5 continents.
The activation possibility of the eSIM feature might differ by country and/ or model version of the device. Ubigi is not responsible for this inconvenience.

3G in Nouakchott Mauritania
We had only 3G in Nouakchott - Mauritania, which is fine for sending some photos and text messages. For serious data transfer or connecting with VPN networks, the speed was too slow.

User friendly process. The data plan started with a single click, once the plan is purchased.

Extremely cost‑effective service with an e‑SIM that is easy to install (note that as opposite to some of its competitors you get new eSIM per country - but that's not an issue for me).
Ubigi was one of the first players in this field, and while the market today is full of companies offering travel eSIMs (and I use a few of them), there have been only few cases in which Ubigi did not offer the best deal.
Coverage in many off‑beaten‑track areas is very good: if Ubigi cannot connect, it pretty much always means that there is no any network and my current telco SIM (despite the high cost of data roaming) will not connect either.
The only issue I have faced is running out of credit and not being able to buy an extra package until I was on WiFi. However, during my recent travels I believe I was able to purchase an additional package over the mobile network even after my Ubigi data had been exhausted.
