The Free Mobile bill is not just a payment receipt. It is a contractual document whose reading is essential for quickly detecting pricing anomalies, especially since the adjustments to pricing grids observed between 2025 and 2026.
Displaying numbers on Free Mobile bills: the setting most subscribers are unaware of
By default, Free masks part of the contacted numbers in the “consumption” section of mobile bills. Only the first six digits are visible, including voice, SMS, and MMS. This truncation, motivated by confidentiality, complicates line-by-line control when trying to identify a premium call or an SMS to a short number charged outside the plan.

The option for full display can be found in the Mobile Subscriber Area. It can be activated and deactivated at any time, at no extra cost. Once activated, each number appears in full on the following bills. We recommend activating it upon subscription and then deactivating it if a third party has access to the account (in the case of a shared family plan, for example).
For those who want to know everything about the new Free bill, this setting is the first lever of transparency to exploit even before analyzing the amounts.

End of “launch price” discounts: understanding the increase on your Free bill
Several Free Mobile plans marketed with a promotional “first year” price see their price automatically increase at the end of this period. This mechanism particularly affects subscribers who signed up in 2025 or early 2026. The increase is not a billing error but a switch to the standard rate provided for in the contract.
The problem: the mention of this switch appears in the general conditions, which are rarely reviewed after subscription. On the bill itself, no specific wording indicates the transition from the promotional price to the full price. The amount changes, without any visible explanation in the details.
Check the end date of the promotion in the subscriber area
The Subscriber Area displays the subscription date and the active plan, but not always the exact end date of the discount. We find that the most reliable method remains to compare the previous month’s bill with the current bill, line by line. A difference of a few euros on the “subscription” line without a change in plan almost systematically indicates this pricing switch.
In case of doubt, the contractual summary sent by email at the time of subscription mentions the duration of the promotion. This document is authoritative in case of dispute.
Added options and suspicious lines: reading the Free Mobile billing details
Groups of subscribers report bill increases without apparent changes in consumption. In the majority of reported cases, the origin is an option activated by default or added during a plan change, not an overcharge in the strict sense.
- Options like “mobile guarantee” or “breakage insurance” can be checked during a device renewal through the Free store. They appear on the bill under a label distinct from the main plan.
- Roaming charges outside the EU are not always identifiable at first glance: they appear in a separate section, sometimes on a different page of the PDF.
- In-app purchases (premium content, premium-rate numbers) are grouped in a “third-party services” section, the total of which can be surprising if the detailed bill is not consulted.
The reflex to adopt: systematically download the complete PDF from the subscriber area rather than relying on the total amount displayed on the dashboard.
Changing Free Mobile plans mid-month: real impact on the bill
Changing your Free Mobile plan during a billing cycle generates a prorated charge. The new rate applies on the day of the change, and the current month’s bill reflects both plans on a prorated basis. This mechanism is standard at Free, but the resulting bill displays two distinct subscription lines, which can lead to the impression of double billing.
Billing period and activation date
The Free Mobile billing period starts on the activation date of the line, not on the first day of the calendar month. A subscriber who activated their SIM card on the 8th of the month will see their billing cycle run from the 8th to the 7th of the following month. This peculiarity explains the frequent discrepancies between bank withdrawals and the calendar month that some subscribers interpret as “advance” payments.
Free Mobile consumption tracking: what the subscriber area shows (and what it doesn’t)
The Free subscriber area displays data, voice, and SMS consumption in near real-time. However, out-of-plan consumption often only appears on the bill, with a delay of several days. This means that data overages abroad or calls to special numbers will only be visible in the tracking later.
- The data counter resets on the anniversary date of the line, not on the first of the month.
- Consumption alerts via SMS do not cover third-party services or premium-rate calls.
- The bill history can be consulted for several years from the subscriber area, in downloadable PDF format.
For rigorous tracking, we recommend cross-referencing the subscriber area counter with the details of the latest PDF bill. This is the only way to spot a discrepancy between estimated consumption and actual billed consumption. The dashboard does not replace reading the bill, it complements it.
The key takeaway: the Free Mobile bill is a more detailed document than it appears, provided you activate the right display options and methodically compare each line from month to month. Price increases related to the end of promotions and discreetly activated options represent the two main causes of surprises on the statement.
