Isn't this £5 + £1 of credit?

there is actually £6 worth of credit between the two sims, can you edit the title op please

Looks like credit will be valid for 90 days max only - from the Terms & conditions (unless the sim-pack says otherwise?).

Yes it says after 90 days the credit will be gone, but will you still be able to make phone calls and texts free to each sim?

So, after the first 3 months, do you need to top up every month to be able to continue with free calls between the SIMs? Or as long as balance is there, it's fine?

thank you ordered 100 sim cards for reselling on ebay... lol :stuck_out_tongue:

In case it's useful to anyone else, the per MB data cost with these SIM's is 19p per MB. So the SIMs look okay for calls and texts between the 2 SIMs, but less useful if you need any quantity of data at a reasonable per MB rate.

Yes, that's a possibility, you can buy 500MB Data Pass that lasts for 30 days for £5, using the credit on the SIM that has the £5 credit on to it. So effectively 500MB of data for £1.99 and you will still have £1 credit left on the other SIM.
