I ported from Verizon to the GSMA plan. eSIM activation took 10 minutes, calls and texts were instant, and data is fine except at a crowded stadium. App billing is straightforward and the free international calling to Mexico was a nice perk.
SSD from a marketplace seller had SMART errors. RMA required back-and-forth and restocking talk, but I documented tests and got a full refund. Lesson: check if Newegg ships it or a third party and read that seller’s policy first.
