IE, the network just did not appear and there was no service.
I did the obvious, turned off the phone, removed the battery and cleaned the simcard and connectors and reassembled. Still... no network.
The Simcard still boots and functions but there is not service showing and the usual message "simcard registration failed" does not appear in this case, I swapped over a mates phone (on account) and still no service on his phone with my prepay, obvious it's not my phone.
A call to 777 (0800 800 021) on monday morning.
First operator said "your phone is faulty, I mentioned I had tried 3 handsets including a 3g which all had no problems with other simcards and only showed no coverage with mine inserted. No, according to him it was my phone.
Next operator checked my account and did a detailed search of the network side of things and suggested I get a new simcard pack.
I sent an SMS to 282 to tell me what SIM pack I needed and it said "this service has been discontinued, please see a vodafone retailer"
On thursday I go to Vodafone retail botany downs and was greeted by a very arrogant salesman whom made me pay for the sim pack and then makes me wait another 10 minutes while he sorts out his own error with the actual sale. He then tries to place it through the system, and it spat out an error.
He then told me to ring 777 to get it sorted. 3 operators later I spoke to one whom worked for Vodafone Au before and seems to know a bit more, he tried to get it through the system and investigated it deeper but still could not get it running. and said he'd call me back after escalating it further, He actually did call back the first time to let me know no resolutuion had been found yet. He forgot to call me back a second time.
I phoned in on saturday and spoke to someone, apparently the escalation was still held up and there was no end in sight. Useless!
Still not working at 10:30 on a Sunday night, 7 days since it went off the network..... I phoned Vodafone and was greeted by an extremely nasty guy whom was extremely rude and told me to call back after 8am tomorrow as he did not have access to tell me what SIM2 pack colour I needed to get.. I became very irate as this point and he said "he does not have access" and I need to call back after 8, I said I KNOW you can access this information, Just tell me and stop wasting my time, greeted with his snarky "you need to call back after 8" So I asked to speak to the team manager, was told they don't have one for the night shift.... bullsh1t!!!!
I called back immediatly by a lovely lady whom advised me of the correct colour packs that go with the HLR's for the numbering ranges and politely confimed with me....
THE STUPID D1CKWAD AT THE VODAFONE RETAIL STORE SOLD ME THE WRONG COLOURED SIM2 UPGRADE PACK... an HLR3 Green pack instead of an HLR4 blue pack
OH MY GOD!!! what monkeys do they have working there... I had lost confidence in Vodafone recently and this is the icing on the cake...
Asides the man whom tried his best on wednesday and the lovely lady tonight whom was very pleasant, They have a long long way to go before they restore my confidence. and..................... my stupid Pre Pay is still as dead as ever...
*************update.**************
Today I switched on the phone and the phone came up "sim registration failed" which it was not doing before (shows there is an obvious fault)
I phoned a useless guy at 777 (He had no idea what a ki string or an HLR was, so well trained!)
He advised me that the Simcard number was indeed the new number. ARGH!
It seems tech support had apparently "actioned " the request and hooked up a HL3 simcard to an HLR4 number

Today (Monday 8 days on) I took the green simcard pack back and they swapped it for a blue pack with no questions and did the swap over and I was back in business.
LONG LAST. I can now make those $2 for ten minute calls I have been making at $1 a minute on my 027.
Glad it' was finally sorted and thanks for all the help from those of you whom know who you are.
