SIM cards & keeping a number

Portugal still sells anonymous prepaid SIMs. In May 2026 the government approved a draft law making prepaid identification mandatory and sent it to Parliament, with a one-year transition for existing cards (reported by Público and others); no approval was found as of September 2026.

Keeping a number depends on the tariff type. MEO’s prepaid terms split tariffs in two: with mandatory top-ups, once validity lapses the card can only receive calls for 90 more days, then expires; without mandatory top-ups, one non-free call made or received every 90 days keeps it active. Vodafone and NOS offer similar no-mandatory-top-up tariffs (search excerpts only, not listed separately).

MEO prepaid (no-mandatory-top-up tariff)

Number-keeping SIM

Network: MEO’s own network (MNO)
Price: SIM price varies; on tariffs without a maintenance fee, €1.80 is charged as an “inactivity fee” after 30 days with no traffic, payment or top-up (notified by SMS)
Keeping the number: MEO prepaid terms: on no-mandatory-top-up tariffs, make or receive one non-free call every 90 days to stay active. Without that, the card becomes receive-only for at least 30 days (extendable up to 180 days if it keeps receiving paid traffic), then expires and remaining balance and points are lost. Mandatory-top-up tariffs become receive-only for 90 days after validity lapses, then expire; a top-up within 90 days reactivates
ID check: Generally no ID for now; the mandatory identification bill is before Parliament
SMS & calls: A normal Portuguese number. Per third-party guides, MEO prepaid roaming outside Europe is enabled after €15 of cumulative top-ups, charged from balance; cost of receiving SMS in China not verified

Pros

No ID needed for now
One non-free call every 90 days keeps it

Watch out

€1.80 is charged after 30 days of inactivity, so an idle card pays every month
If the ID law passes, existing cards must be registered within the transition period
Cost of receiving SMS in China not verified
