There are two main reasons explaining why you can't use Internet Services on your BlackBerry:
BlackBerry Services is not active
When you are using a BlackBerry on giffgaff, you can make calls and send texts whatever the goodybag you choose. However, to use BlackBerry Services, such as BlackBerry Messenger, you will need an active 3G goodybag.
After purchasing a 3G goodybag, go to "My giffgaff". In the "My profile & settings" section, you'll be able to activate BlackBerry Services.
You will need to activate BlackBerry Services to use the following services:
- Receive true BlackBerry push email from up to 10 different email accounts
- Use the resident BlackBerry supplied browser to access the internet
- Install applications over the air (OTA) via the supplied resident browser
- Use BlackBerry Messenger and send PIN-to-PIN messages
Devices running BlackBerry 10 do not need BlackBerry Services to be activated.
Your phone settings are incorrect
If you activated BlackBerry services but are still unable to use it - or use Internet - the issue is probably coming from your settings.
