Unlocked SPV E650 constantly searching

[Guest the hamster]

Hi all, 1st post so be gentle.

Got an spv e650 and set about unlocking it. Ive had a C550 and 600 in the past so read up about it 1st.

Sent £20 to a company that I got the link from on here who could unlock it via IMEI and got the code/software.

Ran the unlocker but when I inserted the sim it just says "searching".

Did a hard reset on the phone and tried again but it still says "searching".

Tried a manual network scan but it wont do anything, just says searching.

Can anyone give me some advice please.

Many thanks, Hammy
