Which network is best in Mexico?
Opensignal's October 2023 report gave Telcel the coverage-experience win (8.8 vs AT&T's 4.4), though AT&T spent slightly more time connected. Its measures focus on populated areas, so remote regions are not covered by that data.
What is the best eSIM for Mexico and nearby countries?
A regional plan: 20 GB, valid 90 days covering 3 countries for $31.39 on 4 Nov 2026. Check that its list includes every country on your route.
Is an eSIM better than roaming in Mexico?
For data, usually. Two weeks on Verizon TravelPass is $84.00 a line (Verizon, checked 5 Nov 2026); NUM’s two-week pick was $9.79 on 4 Nov 2026. Keep your home line for calls.
Will it work on my phone?
Dial *#06# on the phone you’re taking. If you see an EID number, it takes an eSIM. Every iPhone from the XR and XS on does, and the SE from 2020, as do Google Pixel 3 and later and Samsung Galaxy S20 and later. The phone must be carrier-unlocked. Not sure? Text PHONE and your model and we’ll check.
Does it come with a phone number?
No. It’s a data-only eSIM. WhatsApp, LINE, iMessage and FaceTime all work over it, and your home number can stay on for calls and codes.
