When say back up and reset do you mean back up / reset phone again ? Or just network reset ?
And should the above be done with her usa sim i stalled ?
She does have a uk giffgaff sim there
Thanks again for the advice
Does or should it matter if the usa sim is in at the time ?
If doesn't work would it be viable to factory reset with the usa sim installed
Thanks again for the reply will keep the post updated
Ok so wife tried the above and still the same
Contacted samsung uk provided receipt of purchase . Promised code within 48 hrs and still nothing they said 4 times i never attached original receipt which i followed up with emails showing i did .
Then told 14 days for a region unlock code then 48 hrs agai
Contacted samsung usa who said if i was in the usa as its my phone i could phone and be unlocked asap .
Unfortunately i cant phone tbe toll free number from the uk
Any other suggestions .
Everything works untill switches to usa network the says not recognised
Tried a giff gaff uk sim . Came up giff gaff then switched to t mobile then error again
Any more help be great
Well still getting no where and just being lied to by samsung day after day .
Contacted on the 9th November and i contacted again on the 10th November with proof of purchase of the phone .
No one reading messages .
No one reading emails just copy and paste answers .
Explain i had the phone for two years in the uk with a uk sim and it never left the uk so this should in theory make the phone region unlocked ?
Explain that the phone is in the USA that it works with all uk sims .
When my wife puts in a sim from uk in it . I did test before shipping over to my wife!!
It shows ( giff gaff ) then the network changes to T mobile then sim not detected.....
Any usa sim just comes up sim not recognised
Have chat scripts saying it will be sorted by end of day
Chat scripts saying 24 hrs / 48hrs /14 days
Also chat scripts and emails saying mid way through this period it will be 14 days from then that ill get a code
Not one has said the problem could be something else
I even contacted samsung Usa.
They gave me a ticket number and a toll free number to call .
Only issue cant call toll free from the uk as need to speak with phone owner.
But said it would be sorted in ten mins once i do
So im still on the assumption its somehow still region locked and needs a code of sorts .
Possibly enter from key pad via hidden menu ?
Only thing i done befire sending but after checking the phone was ti factory reset the phine then test .
Then reset again and ship
Any help would be great
