Tesco Mobile vs giffgaff Trade-In and Phone Upgrade Guide (2026)

Separate the old phone, new phone and SIM

People searching tesco mobile vs giffgaff upgrade offers can easily compare a trade-in quote with a monthly handset figure and miss the rest of the bill. Treat each part as a separate decision. A strong old-phone quote does not prove that the new phone has the lowest total cost, and a low monthly figure may still include an upfront payment, a long repayment period or a new airtime commitment.

Start the Tesco Mobile route with eligibility

An existing Tesco Mobile pay-monthly customer should check My Account or the app before comparing advertised deals. Tesco says an early upgrade fee may apply before the end of the contract. A tariff change or upgrade in the previous month, or unpaid recent bills, can also stop an upgrade for the moment.

1. 1

   Open the account upgrade screen

   Record the eligible date, any early fee and the offers actually available to the account.
2. 2

   Calculate the handset total

   Add the upfront amount, every device payment and the airtime cost over the relevant period.
3. 3

   Quote the old device separately

   Tesco Mobile currently routes trade-ins through Assurant for an initial condition-based valuation.
4. 4

   Choose the payout

   After inspection, an accepted device can be paid by bank transfer or Tesco e-gift card under the current route.
5. 5

   Compare the net cost

   Subtract the final trade-in proceeds, but retain the early fee and all airtime charges.

Keep the quote, photographs and proof of postage. If the inspection changes the value, review the revised amount and return option before accepting it.

Use giffgaff to keep the handset and SIM decisions flexible

giffgaff sells unlocked new and refurbished phones. Existing members can keep using their current SIM, number, credit or plan. If the replacement needs a different SIM format, a SIM swap can move the number and service instead of opening a new line.

A new member buying a new handset currently has to add a non-refundable first SIM plan of at least £10. Some refurbished condition grades are exempt, and the checkout shows the applicable requirement. A handset can be paid in full or, for an eligible applicant, through Klarna. Klarna eligibility includes age and UK-address requirements and remains subject to approval.

The old phone can be sold separately through giffgaff Recycle, which giffgaff says is operated by Likewize. The service gives an initial quote, inspects the posted device and can pay an accepted sale to a bank or PayPal account. A revised quote can be rejected for a free return under the current help-page terms.

If this route fits but a physical card is still needed, see the giffgaff physical SIM. Check whether the checkout contains a phone, a SIM plan or both before paying.

Compare both routes on one cost sheet

Compare the same model, capacity and condition. For refurbished phones, include the grade and warranty rather than comparing the headline price alone. Treat an e-gift card as cash only if it will genuinely replace Tesco spending you planned to make.

Prepare the old device before posting

1. 1

   Back up the data

   Move photos, messages, authenticator entries and important files before erasing anything.
2. 2

   Remove account locks

   Sign out of Apple iCloud, Google or Samsung and turn off device-finding protection.
3. 3

   Record the device

   Save the IMEI, serial number, capacity, colour and battery information used for the quote.
4. 4

   Photograph the condition

   Capture the screen, edges, cameras, power-on state and packing process.
5. 5

   Factory-reset the phone

   Confirm the backup works, erase personal data and remove the SIM and memory card.
6. 6

   Keep postage evidence

   Retain the tracking number and proof of posting until the final payment clears.

Choose by the route that is complete

• check_circleChoose the Tesco Mobile upgrade route when the account is eligible, the early fee is acceptable and the combined handset and airtime total works for the full term.
• check_circleChoose the giffgaff route when an unlocked handset, a reusable existing SIM and separately managed phone payments are more useful. Quote the old phone independently.
• check_circleWhen totals are close, compare the final old-device payout, warranty, first-plan requirement, early fee and payout form instead of the homepage monthly figure.

Order only when the old-phone route is chosen, the replacement handset total is known and the number and SIM have a clear next step. If one line is still missing, return to the eligibility screen, inspection terms or checkout before paying.
