Sim Card Electric Gate

How about a sim from RWG Mobile. rwgmobile.wales/web…ge/.


£35 for 2 years or £20 for a year. Given they are a fixed plan, I don't believe they would be deactivated.

Cant you add a sim to your own existing account or get a monthy/yearly contract sim ?

Might cost you a couple of pound extra per month but I do not think sims last longer than 6-9 months without activity?

I am sure someone will correct me.

We used contract sims, just went with the cheapest with minimal data, anything else just seemed a load of messing about.

If it only has to accept calls can't you just use a free PAYG SIM that works straight away without top-up? I think Asda, Lebara and Vodafone Sims will do, then just replace them when they get disconnected after whatever the time limit is.
Just had a look at Asda out of interest and once you've topped up the SIM it's active for 180 days, then you can't make calls but still accept them for another 90 days until you get cut off so in that scenario you'd pay £10 for 9 months or I'd guess without topping up it would last 90 days.

I have a Vodafone sim in an old phone that has not been topped up for almost 3 years and has not sent a text or made a call for that long. It is still active and can receive calls and texts.
I also have an O2 sim in a gate. Ours is programmed using text messages and has the ability to reply to texts (for system status etc). if yours can do the same, maybe just get it to send a text every so often. In our case all deliveries have to use the intercom on the gate to contact us so it makes regular calls from that.

Or you just remove the SIM a few days before it is due to be deactivated and make a call then put it back again
