Yes. The Service Book carried a lot of information that these days people take for granted on most devices. And with the APN down and nothing handshaking and serving a default service book (which, incidentally, was served over a proprietary TCP connection IIRC), the phone just won't get the right configurations.

That is why I said it _should_ still work for base calls (and likely SMS), but nothing else, really.

I edited an old service book to gain MMS functionality on my Bold 9900. My carrier (Koodo Prepaid, Canada) doesn't have BIS and never did. If I lose any other functions, I'll probably have a look at the other service books to find out what's in there.
