how long will my credit last on 02 payg sim?

[Anonymous]

Hello, I hope someone can help me.  I've bought a payg 02 SIM - I opted for the 'big talker' tariff but I have got this SIM for a phone I only intend to use occasionally - I do not anticipate needing to top it up £10 every month as I'll mainly use it to receive calls and occasionally check voicemail.

My question is this: how long will my credit stay on my phone?  Will it be deleted after it has been on my phone for a period of time?

Thanks ever so much.

That amount will stay their indefinitely as long as you keep the sim live by topping up by 999 days and make a call every 6 months.

If you top up £10 it will give you 3000 O2 texts and 50MB data which is valid for 30 days, but the £10 is retained to use as you wish.

Sorry I ommitted to add -> This is the terms of the Big Talker Tariff http://www.o2.co.uk/help/pay-and-go/big-talker

Be aware voicemail does not come out of your minutes for PAYG.

It's 15p per call to use voicemail.
