So looking for some advice and what options exist as I have zero experience with mobile plans, as for the last 15 years I've just had a work phone for both business and personal. After finishing my employment earlier in the month and needing to keep my number I jumped on the Coles 365 day Double data plan deal posted on OzB. The issue now is that we are planning to go overseas for three months and the plan doesn't have any Global roaming options.
So as far as I see it my options are:
1) Leave it as is and pick up a SIM card overseas.
Issue- this effectively make my phone number un-contactable, so I'm screwed if I need to get onto a service like the bank that requires SMS verification, Does WhatsApp still receive messages in the scenario?
2) Get a new cheap pre-paid that I can port my number to.
Issue - If if Port my number, do I kill the current Coles deal and lose all my data, or can I port it back to this SIM once returning to Australia
3) Leave my SIM in an old phone in AUS, and get a new SIM and forward the number.
Issue - I won't be receiving the SMS on the phone overseas.
If anyone can help with what would be the best way to deal with this.
Edit: So my current SIM has the following remaining - so while switching to ALDI $15 would be a no brainer, I'm concerned about forfeiting a lot of data that I already paid for.
334 Days remaining -> 108.6GB Data
Also, I am absolutely not interested in making phone calls, its only to make sure I am contactable from home and not being locked out of banks or crypto exchanges requiring some kind of SMS identification. So my main question at the moment is, can I port out and then back into the Coles SIM (sounds doubtful)
Grab a cheap SIM when overseas - global roaming is stupid that long term.
Either tell people your new number or have someone check it here?
