Supported account routes
Three’s support currently covers replacement eSIMs for monthly and PAYG customers through My3 or the Three app. Check which process applies to your account.
Installation preparation
Confirm the exact phone model, stable Wi-Fi and access to the account. Use only the profile issued through Three’s official process and keep its activation details private.
Handset changes
Read the transfer instructions before deleting the previous profile. An operating-system transfer feature may depend on the provider and model. Ask Three whether a replacement profile is needed.
Trouble during setup
Note the displayed error, whether the profile appears in settings and which line is selected. Contact Three rather than repeatedly deleting profiles or scanning the same code.
