Leaving voicemail messages and inbound calls not working at all in Brazil
I am currently in Brazil with my Smarty sim. Before leaving UK, I diverted all calls to a UK landline number. This worked for the first 2 days, but now I discovered that anybody trying to call my Smarty number, gets the audio message "It has not been possible to connect this call. Please try again later". I am still receiving text/sms messages. I have used the codes from here (#002#) https://help.smarty.co.uk/en/articles/1463317-setting-up-call-forwarding to cancel all diverts - but that didn't make any difference. I contacted Smarty support, who, after asking me to reset the network settings on the phone, then giving me some codes for Apple phones (although we discussed already I am on an Android phone), now they tell me voicemail doesn't work when roaming in Brazil, unless I buy an add-on. By that, they mean people can't even leave a voicemail message. Which I'm fairly sure is non-sense - unless anybody knows otherwise?
I am at the point of assuming that something has gone wrong at network level, and Smarty have no idea what is going on and are just fobbing me off. Does anybody have any idea what else I could try please? I am kind of guessing I am most likely stuffed until returning to the UK.
