Overall, bad signal and no customer service.
I have also contacted your customer service, but did not get any assistance. The signal went of frequently, while other people around me had data. I often was trapped, when needed signal / data. Website and google maps loaded slowly.

It didn’t work. Tried many things, followed all instructions and got help from a phone shop. It didn’t work. Bad experience.

Dear Natalie, Let me deal with your situation. We see that you activated eSIM and connected to the Internet on December 28th at 18:49 (GMT). You may not have mobile data roaming activated, or you are out of Movistar's coverage area. We will send detailed instructions to your email. In any case, please accept our apologies. Regards, Onesim Team
