In the United States, most radio transmitters must be type accepted
(certified) by the Federal Communications Commission.  Modification
voids the type acceptance, so operating a modified mobile phone on its
original frequencies would be illegal regardless of what the phone
company's rules say.  However, no certification is necessary for
transmitters operated according to the rules for the Amateur Radio
Service.  Thus, an licensed amateur could legally use a modified mobile
phone, provided it transmitted on frequencies allocated for amateur
radio and met the other requirements for amateur operation, including
not causing harmful interference to other services.

This has been the situation in the US for many years, and I believe
almost all countries are at least as restrictive.
