You can get a special hole punch device that can trim your sim card with precision. It depends on which sim card you currently have. Also you can get adapters to convert a micro sim into a normal sim (basically a jacket for the sim card). If your on o2 go into the store and they'll do it for you (ttansfer contacts, not cut the sim)
Yeah I'm on O2
Problem is that I can't keep my BB and the HTC. The HTC is a replacement so they're taking the BB back when they deliver the HTC to my house
Can I just take my SIM card (regular one) into the O2 shop and ask them to transfer my contacts to a micro-SIM with my current mobile number on it?
