Looking for some help on OSF. Would appreciate a little help.
I had purchased a OSF in March. I unlocked and rooted the phone and was using a vodafone sim in it. I have now switched to giffgaff now but the new giffgaff sim is not working. When I press the dial button, the phone displays Call Ended immediately.
I am not using the orange SIM so cannnot go to Orange for Help.
Giffgaff sim works in another phone so it is not a giffgaff problem.
The phone is unlocked as I was using the vodafone sim in it for 3 months.
I just cannot go past this Call Ended screen everytime I dial a number.
Hope somebody can tell me what can the solution be for this issue.
Many thanks in advance for your kind help.
