Our verdict
AT&T Mexico suits people already living in Mexico who want a network's own coverage with sim only, 5G and eSIM in one place. Entry is MXN 299 and the unlimited plan costs MXN 1,449, so the price gap between tiers is the thing to weigh.

Pros and cons
Pros
- Sim only, 5G and eSIM are all available, so a phone you already own is enough to start
- Data rollover is offered on prepaid plans, which suits a light month after a heavy one
- Roaming spans 77 countries, a broad footprint for a single network
- Entry price of MXN 299 with an unlimited plan at MXN 1,449, both sold by the network itself
Cons
- A credit check is required, so the contract and rolling plans sit behind a credit decision
- Billing runs contract, rolling and prepaid, so a rolling or contract term is available and the monthly figure can be tied to a period
- The unlimited plan at MXN 1,449 sits well above the entry price of MXN 299, so heavy use pushes the bill up sharply
- On price from it ranks 213 of 258, further down the field than its 171 of 173 rank on unlimited price
Who it suits
- Households in Mexico that want a network's own coverage rather than a resale
- People who travel to and from Mexico and want roaming across 77 countries
- Sim only buyers who want rollover on prepaid and 5G together
Who should look elsewhere
- Buyers chasing the lowest entry price, where yesss lists a plan at €0
- People who want to compare a prepaid and contract range, where GETESA bills on prepaid and contract
What it does well
The feature set comes straight from the network rather than from a thin resale. Sim only is available, so a handset you already own is enough to start. 5G is offered, which matters on a newer phone in a busy city. An eSIM is available, so a second line or a new device can be set up without waiting for a physical card. Data rollover is offered on prepaid plans, so data left over can carry into the next month rather than disappearing. Roaming covers 77 countries, which is a broad footprint for one network and useful for trips outside Mexico. A credit check is required, so the contract and rolling side of the range sits behind a credit decision, while the prepaid side gives a quicker route in.
Where it sits among rivals
On price from, AT&T Mexico ranks 213 of 258, which puts the entry price below the middle of the field. On unlimited price the picture changes: 171 of 173, much closer to the front of the list. That gap is the trade-off to weigh. The entry tier is priced for a lighter data allowance, while the unlimited tier sits far higher, so the range competes on what sits inside the plan rather than on the smallest monthly number.
Pricing
Plans start at MXN 299 for the entry tier, with the unlimited plan at MXN 1,449. The gap between the two is wide, so the choice comes down to how much data you actually use each month. Both figures are the ongoing monthly cost rather than a first-month promotion, so budget the same amount at renewal. Anyone who needs a larger allowance than the entry tier carries moves to the top of the range, where the monthly figure steps up sharply. Reading the two prices side by side is the quickest way to see whether the extra data is worth the extra cost.
Who runs it
The plans are sold by AT&T Comercializacion Movil, S. de R.L. de C.V., the AT&T commercial entity operating in Mexico, so the seller is the network itself rather than a reseller or an MVNO. Support runs on email, chat and phone, which covers email, chat, phone and a help centre. Because the network is the seller, coverage, roaming and the plan terms all come from one operator, with no third party between the customer and the tariff.

Frequently asked questions
How much does AT&T Mexico cost at entry?+
The entry tier starts at MXN 299 a month and the unlimited plan is MXN 1,449. Both are the ongoing monthly cost rather than a first-month promotion, so the same figure applies at renewal. The wide gap between the two tiers is what decides which one suits the data you actually use.
How does the price sit against other sellers?+
On price from it ranks 213 of 258, so the entry price sits below the middle of the field. On unlimited price it ranks 171 of 173, much nearer the front. The two rankings read together describe a range that competes on plan content rather than on the smallest monthly figure.
Do AT&T Mexico plans need a credit check?+
A credit check is required on the postpaid side, which covers the contract and rolling options listed under contract, rolling and prepaid. Prepaid is the other billing type on the same site. Anyone who cannot pass a credit check should read the prepaid route first, since the contract and rolling tiers sit behind that decision.
Where does AT&T Mexico work and how far does roaming reach?+
The plans run in Mexico, so this is a home network for Mexico rather than a travel product. Roaming reaches 77 countries, which is a wide footprint for a single operator and useful for trips abroad. Anyone who needs a permanent home network elsewhere should treat these plans as a Mexico line with travel cover on top.
Does AT&T Mexico offer eSIM and 5G?+
An eSIM is available and 5G is offered, so a newer handset can use both without swapping a physical card. Sim only is available too, so a phone you already own is enough to activate a line, and the entry tier starts at MXN 299. Devices that support eSIM and 5G get the most out of both features.
What happens to unused data on prepaid plans?+
Data rollover is offered on prepaid plans, so data left at the end of a month carries into the next period rather than expiring. That suits a light month after a heavy one. Prepaid is one of the billing types listed under contract, rolling and prepaid, so it sits alongside contract and rolling rather than being a separate product line.
Do I need a new phone to sign up?+
Sim only is available, so a handset you already own is enough to get going. An eSIM is also offered, which allows a line to be set up on a compatible device without waiting for a card to arrive. The plans are sold by the network itself, AT&T Comercializacion Movil, S. de R.L. de C.V., rather than through a reseller, so the terms come straight from the operator.
How do I get help from AT&T Mexico?+
Support runs on email, chat and phone, covering email, chat, phone and a help centre. Because the network sells the plan directly, the same organisation handles coverage, roaming and billing questions rather than passing them along. A call covers urgent cases, with chat and email for everything that can wait.
