yesterday I bought this tele phone card ,I signed in my account and
downloaded my o2 app successfully. but i can not use the internet data
to explore.i just think it cost me 15 pounds but it can not give me15Gb
in the store, the seller took the card to me and told me the PIN number
，she did not know how to activate the sim, so I just want to know how to
activate the sim
my phone signal showing H+ or 4G, I can receive the message and phone,i
did not do network settings,by the way, i do not know why my balance is
0 because the card cost me 15 pounds.
