Charged for data roaming

[CiaranLowe]

When looking at my data roaming bill i have been charged 41 for being in bosnia even though i have only been in croatia. All the other times ive used data in croatia it hasnt charged me and i have not been to bosnia so not sure why i have been charged 41

Croatia is included in the roaming passport, however Bosnia is not.

Bosnia is a 'Rest of World' tariff and you are charged for usage.  It's quite expensive...

Although you've been physically inside Croatia you must have connected (probably automatically) to a Bosnian carrier.

(I would recommend always using manual instead of automatic network selection if you are travelling in an area where it's possible to connect outside of it)
