There are several problems with buying B&You SIM cards from eBay:
- They will not be registered in your name, but to the original e-mail address that ordered them.
- They are unlikely to be nano-SIMs. One should always buy nano-SIMs now, given that a nano-SIM can be easily enlarged with a free adapter but a larger SIM cannot be so easily reduced in size when newer phones start taking smaller SIMs. Given the difficulty in receiving the SIM in the first place, it is likely to be just as difficult to receive replacement SIMs.
- The price is three times the normal price.
