Great experience with this Mongolia eSIM. Activation was quick, internet speed was fast and stable, and having unlimited local calls and SMS made traveling stress-free. Excellent value for money. Would definitely use again.

Ulaanbaatar is the only place where you can get a good signal, but Terelj has no signal at all, so be careful (T_T)

The e-SIM worked fine, except for the three hours of Maya outage from December 31st to January 1st, 2026. Otherwise, the connection was fine, including calls. I was traveling to Goa.

I refreshed many times before my 3 esims finally appeared, which wasn't a good experience. I suggest optimizing this aspect, otherwise it's okay.
