Unlock SIM-locked Phone

How easy it is depends on the make and model of phone - what is it?

Belgian networks do not lock phones to their network so it is more difficult to find shops to do it here. Your best bet might be eBay, just look for someone with good feedback

I know negative answers aren't that helpful but...

I had the same problem with an iPhone 4 that my daughter passed on to me. I firstly tried my provider (mobistar) and they said 'no, try some of the places in Matongé'. I did that and one thought they could get the codes to do it, and promised to call me back but never did.

In the end I did it in London.

What is the Brand and model of your Phone?

The country of origin and network company name ?
