Sounds like my new tablet Neil. I purchased it for my multi-rotor work and put it into a 12 month plan so that map data could be downloaded. Aussie Telco could not give me the long term plan on line as the 'clickable link' was redundant, it only gave me the monthly options as ' clickable'.
So went into town and got a lecture from the teenage staff in the local store as to why a monthly account would be nicer until I pointed out that $30 x 12 months was a bit more expensive than $150 for unlimited data for 365 days.
After a bit of calculator work we agreed and I managed to obtain a SIM card for my tablet.
Now my tablet has it's own phone #, disclosed to nobody but already has calls and messages asking me to ring back.
I checked the numbers, all are at premium rates! Looks like I have been sold out by somebody already.
