PAYG sim for an alarm system

[Barry5848]

Hi - we are getting a PAYG sim card to put inside our intruder alarm - for the purposes of dialling out when the alarm alerts us to an intruder. 

We will, of course, put credit on this sim, to enable calls to be made - but the calls will be sparse and infrequent. 

Will this sim card go into hibernation mode at any point ? We need to be able to rely on it when the need arises 

many thanks

Hi @Barry5848. 

Thanks for coming here. 

To keep a SIM active and prevent hibernation you will need to make a chargeable action every 179 days. 

A chargeable action is any of the following:

• Voice and data usage. This includes making calls, sending text messages and picture messages, retrieving a voicemail, and using data that is not within your pack or add-on.
• Topping up your account.
• Buying a pack or an add-on.

Hope this helps, 

Katie
