Hello, new to ID. Before purchasing a SIM I looked for information on the minimum amount of credit it is possible to top up a PAYG SIM with. I found references on the internet to their being no minimum, but nothing on the help pages or in this community. Having now received my SIM and registered it to my account it seems like on the app and the website the minimum possible top up amount is £5. Is there a way to top up less, say £1? It would be handy to know as given the low cost of calls I’m not sure if I’ll get through £5 per year (one top up every 365 days is needed to keep the SIM alive).
