La Poste Mobile is currently running a promotional offer on its 130 GB 5G mobile plan, which includes four months of free service before switching to a monthly fee of 10.99 euros. This deal is available until October 4, 2026. The plan uses Bouygues Telecom’s network and provides 25 GB of data usable in Europe and the overseas departments (DOM), along with unlimited calls, SMS, and MMS. The initial cost of the SIM card is 9.90 euros. Over the first year, the total cost of the plan—including the SIM card—would be 97.82 euros, averaging to about 8.15 euros per month. After the initial four months of free service, the monthly rate goes back to 10.99 euros, making the yearly cost 131.88 euros. This promotion makes the 130 GB plan one of the few options offering more than 100 GB of data for under 100 euros for the first year. In addition to the 130 GB plan, La Poste Mobile offers a 50 GB plan priced at 10.99 euros per month. This plan is specifically for users under 18 and includes SafeBear, a service that helps detect signs of cyberbullying in messages. For users who are 18 or older, the 130 GB plan is typically the better option due to its larger data allowance. If users want to keep their phone number when switching plans, they can call 3179 free of charge to get their RIO number. This number can be provided when ordering a new plan, and the new operator will handle the transfer of the mobile number at no additional cost.
