Tesco Mobile: bills, switching & leaving.

Start with the Tesco Mobile context.

Use the Tesco Mobile app or its official account service for account information. A Tesco shopping or loyalty login should not be assumed to provide every mobile-account function. Choose the correct service and number.

A monthly Tesco Mobile arrangement may involve separate handset and airtime obligations. Read their end dates and balances individually. A loyalty-related condition should be checked in addition to the service contract, not in place of it.

Understand the bill before challenging it

Put the statement period first

A statement date, payment date and usage period are different. A first or final bill can include adjustments that do not resemble a normal full cycle. Read the dates before deciding that a recurring service has changed.

Separate the components

Identify airtime, device repayments, extras and usage beyond the allowance. A single collection can contain several obligations. Removing an extra may not change a handset balance, and leaving airtime may not finish a separate device agreement.

Trace unfamiliar usage

Check the number type, destination and time of each disputed event. International calls from the UK and roaming are different categories. A domestic allowance may exclude premium or service numbers. Do not assume an unfamiliar line is automatically fraud, but investigate it promptly.

Find the notification

If the recurring amount changed, locate the agreement and the provider’s notice. Check whether the item is a scheduled change, an expired benefit or an adjustment. We do not publish current tariff figures because the active account documents determine the answer.

Raise a specific question securely

State which item is disputed, why and what correction or explanation is requested. Use the official account channel and retain a reference. Do not send a complete unredacted bill to a general-information site or disclose card details on an unsolicited call.

Keep the number. Understand the sequence.

Choose the outcome first

For most single-number UK switches, a PAC is the route for retaining the existing number. STAC is the switching route when you do not want to retain it. These are not discount codes and are not interchangeable.

Request the correct code

Ofcom describes texting PAC to 65075 or STAC to 75075 from the relevant line. Multi-number accounts can require the provider’s online or telephone process. A code normally remains valid for 30 days; check the accompanying information before proceeding.

Read the leaving information

Requesting a code does not erase a remaining commitment. Look for early-exit information, credit and device obligations. Keep the answer in writing where possible and distinguish a service charge from a separate handset repayment.

Let the receiving provider organise it

Supply the valid code to the new provider using its official process. Ofcom describes completion within one working day once the receiving provider has the required code and information. Do not separately cancel a number you intend to retain without understanding the consequences.

Check both sides afterwards

Test incoming and outgoing calls, messages and data, then check the final statement and any separate payments. If the transfer is delayed, raise the issue with the receiving provider. Keep dates and correspondence; independent guidance cannot submit or repair a port request.
