Hey customer service is 100% and atm I’m at a remote beach on an island and no one has service here but me! So actually highly recommend 😉😉

Used one eSIM during a stop in Istanbul and another in Riyadh — both activated right away. Fast, reliable connection from start to finish.

My previous eSIM from another provider wouldn’t activate in Rome, so I switched to this one — it connected instantly. The data speed was perfect for maps and sharing photos all week. Zero stress, just worked.
