Step-by-step

1
Buy prepaid on arrival
Telcel Amigo has the broadest coverage in the country and is the safe default if you will drive out to La Primavera, Chapala or Tequila at weekends. Bait, on the Altan network, and weex are cheaper but thinner outside the built-up area. SIMs are sold at OXXO, Walmart, carrier stores and the airport.

2
Register the line to your CURP and ID
Link the number to your CURP and a passport, INE or resident card through the carrier's portal or app. It is free, takes minutes, and is now the difference between a working line and a dead one. One person may hold up to ten lines under a single CURP. Postpaid contracts were registered when you signed them; it is prepaid that needs doing.

3
Keep the number alive with recharges
Prepaid packages expire, typically after 30 days, and an unrecharged number can eventually be recycled. Dial *133# to check balance, data and expiry without using data. Losing a number that receives your bank's one-time codes is a slow, avoidable disaster.

4
Ask the administración which ISPs can actually reach the unit
Telmex, Totalplay and Izzi all cover Zapopan, and symmetric fibre is cheap by international standards. But in a coto or a tower the building's cabling is frequently controlled by whichever provider wired it, sometimes under an exclusivity arrangement with the administración. Ask before you sign the lease which providers are physically available in that unit, because the answer is often one rather than three.
OnlineWho: YouOne to three weeks including an engineer visit
5
Switch to postpaid once you have a bank account
Postpaid plans cost less per gigabyte but require a credit check, a Mexican address and usually a local card or direct debit. Most newcomers qualify after a few months of a Mexican salary. Number portability lets you keep your number; never cancel the old plan before the transfer completes.
OnlineWho: You≈MXN 200–600 a month
6
Have a backup for storm season
The June-to-October storms take down power and sometimes local networks for hours at a time, and the outer Zapopan colonias are typically restored last. A prepaid SIM on a second network, or a plan with generous hotspot data, is cheap insurance for anyone whose income depends on being online in the afternoons.

Things most newcomers don’t know

The registry that came back is CURP-based, not biometric — and it will suspend your line.

The Supreme Court struck down PANAUT, which would have collected fingerprints and iris scans, and many arrivals still believe Mexican prepaid is anonymous. Linking a line to a CURP became compulsory on 9 January 2026, and unregistered prepaid numbers are being suspended on a rolling calendar running from 15 August to 31 December 2026 by the last digit of the number. No biometrics are taken, but a suspended SIM stops receiving your bank codes.

You do not need residency to register a line — a temporary CURP is enough.

People on a tourist entry assume the registration rule locks them out of a Mexican number entirely. RENAPO issues a temporary CURP to foreigners against a passport, free and online, and that satisfies the requirement. It is a five-minute fix that saves paying roaming or living on a travel eSIM for the weeks between arriving and holding a resident card.

In a Zapopan coto, the ISP question is settled by the administración, not by you.

Much of the municipality's newer housing is inside gated developments where the internal cabling was installed by a single provider, sometimes under an exclusivity deal. That can mean no fibre choice, a mandatory bundled package, or a long wait for a second provider to trench. Because so much of Zapopan's rental stock is exactly this kind of housing, it is worth asking at the viewing rather than discovering it after the move — and it is a question a Guadalajara-focused guide will never tell you to ask.

Bait is genuinely cheap but rides a different network from Telcel.

Walmart's MVNO runs on Altan's shared wholesale network rather than Telcel's towers, which is why it costs a fraction as much. Inside the built-up metro area the difference is modest. Drive into La Primavera, out to Tesistán or up towards the barranca and it becomes obvious. If your phone is your only connection and your work depends on it, the extra pesos for Telcel buy the coverage you will actually miss.

Common mistakes to avoid

Never registering the line to a CURP and losing the number and your two-factor codes.
Assuming a tourist cannot register a line — a free temporary CURP solves it.
Letting prepaid credit lapse until the number is recycled.
Signing a coto lease without asking which ISPs physically reach the unit.
Choosing an MVNO on price and then discovering the coverage outside the built-up area.
