Do you not have another SIM with more favorable data roaming rates that you can use just as the trigger? This is what I tend to do though unfortunately you would need a second phone.

If not, you really should consider getting some cheap prepaid SIM just for the data, obviously also useful for SMS services like fishtext. There are plenty of prepaid SIMs available from European carriers that have decent rates. They are discussed elsewhere on this forum.

Betamax really do have the lowest possible rates to IOM mobile that you could ever consider. My experiences with the traditional callbacks are not only that their rates are high, but they are no longer that reliable in picking up a trigger anyhow! The last one I had (run by a small UK company), used to annoyingly call me at all odd hours of the night thinking I had triggered a callback request.
