I have a real problem with the notion that what I agree to in a contract is absolutely binding ("iron clad" against me), but the other side has the right to change the terms in their sole discretion. In U.S. domestic contracts, some courts have started to balk about this. Binding arbitration clauses buried in standard terms and conditions have been tossed in Washington State and California, sole discretion clauses have been invalidated, and the ability for one side to modify the contract at will has started to fall.

I understand the objection to callback services and believe there is some legitimacy to these, but someone who tells his family to call him/her every night or texts his friends and tells them to call him is a different story. Many people get these SIMs because they are free calls to their friends in the UK (if they are on the right plan). When I used to live in Dubai, I packed a dual SIM phone for precisely that reason.
