Your device needs to be unlocked or locked to the O2 network to work with giffgaff. A phone is locked when it can only use a SIM from a particular mobile network operator.
Even though Tesco Mobile also uses the O2 network some of their phones are double locked meaning that they will not accept a giffgaff SIM without unlocking. Unfortunately it is not readily obvious which of their phones are double locked.
You may find that although you are certain of your password the site won't log you in and shows a "wrong credentials" message. The most common reason for this is a browser compatibility issue and can usually be resolved by clearing the cache/cookies and/or switching browser.
Almost always this is due to logging into the wrong account. Because the site allows you to create forum only accounts many people have two or more accounts with similar community member names - sometimes completely inadvertently (e.g. get part way through activating a SIM, stop and then start the process all over again).
This problem often crops up a month later when the original goodybag runs out. The community member wants to buy another goodybag, but not having logged on in the meantime has forgotten their community membername/password combination.
If you forget either your password, membername or the email you registered, you can text 'pass' from your phone to 43430. A reminder and a password reset link will be sent to the number by SMS, within a few minutes.
goodybags are measured in allowances (minutes, texts and data) and not £'s. If you buy a goodybag only (no PAYG topup) then it is correct for your balance to show as zero. Balance only refers to PAYG credit (It does not expire after a calendar month like a goodybag does).
You don't get a goodybag automatically on topping up, they have to be purchased manually. If you top up with a voucher just go to the Top up page to buy a goodybag or see this Knowledge Base article on how to exchange your airtime credit for a goodybag.
When you are using a BlackBerry on giffgaff you can make calls and send texts whatever the goodybag you choose. However, to use the BlackBerry Services, such as BlackBerry Messenger, you will need an active goodybag.
If you are running PAYG then mobile data is charged at 5p per MB in the U.K. as well as the E.U. and select countries. This can quickly get expensive and drain your credit. To keep an eye on your spend you could install a data counter app to warn you when you are getting close to your maximum spend (or whatever limit you require).
If you're unsure on whether you want to use goodybag or PAYG then have a look at giffgaff's best tariff calculator which can help you to work out which giffgaff tariff is best for you.
Make sure the SIM is working properly with the giffgaff number before requesting the transfer.
Make sure the giffgaff SIM works on your phone.
Number transfers are not done at weekends - when booking the request the safest time to go for is midweek or when you know you won't be using your phone.
Don't assume what your transfer date is. The date can be checked on the transfer page once you have requested the transfer.
During the transfer, you will lose service on both your old SIM and the new giffgaff SIM, possibly for several hours. If it is vital that people can contact you, then you will need to make contingency arrangements.
