Just joined giffgaff today. Please could somebody tell me if the giffgaff sim cards expire after 30 days like most other companies. I'm sure somebody told me they don't but can't find that info on website.
@kathydaisy You just need to do ONE of the following to keep your sim active:
13.3. Your SIM Card will be disconnected unless, at least once every six months, your Account is used to:
a) make at least one call, SMS or MMS to another number (not including calls to emergency services or Member Services);
b) make at least one connection to the Internet; (mobile data NOT wi-fi)
c) make at least 4 received calls of more than 10 seconds;
d) make at least one airtime credit or Bundle purchase; or
e) receive Payback Points.
13.4. If your SIM Card is disconnected, you will lose any remaining credit or Bundle balance on your Account and if you wish to be re-connected, you will be given a new mobile phone number.
for more information
