No problem. I agree with you about cutting mini-SIMs to micro-SIM size. I always prefer a proper micro-SIM too. The chip on some mini-SIMs (even recent ones) is larger than a micro-SIM, which doesn't inspire me with confidence either. GiffGaff should just do what operators like AmaySIM do and issue a
universal SIM that can be snapped out in the desired size. No network needs to issue separate SIM sizes.
