First of all - I myself is a telecomunication engineer working for one of the leading vendors. I called their helpdesk when I was trying to send SMS to Sweden but it did not work. But I could receive SMS from that same Swedish mobile. I asked the helpdesk guy about text message agreement between Vodafone and the Swedish operator Tele2. But the guy did not want to listen and kept saying I was using wrong number. I asked how come the same number works when I try from 3-mobile? He didnt answer and asked me to try his suggestion. And his suggestion was to add 0011 instead of + (when you dial overseas from Aus), country code, CITY CODE (which is only applicable for calling land lines) and then mobile number beginning with 0. So, the number for SMS should look like: 0011 46 03 071234567. Or just to explain how dumb that was I am giving example using Australian numbers - 0011 61 03 0411576891.

I told the guy that this would definitely not gonna work cause CITY code is not applicable in mobile number system. But the Indian guy got angry and he was so rude and said - "you first try what I tell you to try. who is the helpdesk? if you know how to do it, why did you call helpdesk? first try my recommendation, and if it does not work, call back again." and he hung up.

Of course it did not work and I called back the next day. Talked to an Australian girl this time and she agreed that what that Indian guy said was rubbish. But still she could not help to figure out why I cannot send SMS to Sweden but can receive.

Finally, after waiting for 3 months without a solution, and facing other issues like no coverage in my bed room, or underground car parks or even in safeway/coles, I decided to move to Telstra. Could be a little costly but their NextG got the best possible coverage.

So yeah - VERY POOR, RUDE, DUMB CUSTOMER SERVICE and VERY BAD RECEPTION.
