Can't text even though just topped up. HELP

[#1]

It won't even let me text people who are on GiffGaff which should always be free and the goodybag must be working as it's letting me call people... But no text!?

[#2]

have you got the giffgaff message centre number? +447802002606

[#3]

did you buy a goodybag after topping up if so and its not letting you txt then you may need to do a manual roam try this
1. Go to settings
2. Go to mobile networks
3. Choose a network other than o2 (gg) ie orange or t-mobile
4. Come out of settings and it will no network coverage
5. Repeat the process this time choose o2 (gg)

this reconnects you to the network and should let your txts come through and allow you to txt i hope this helps happy hogmany
