Hello, happy Monday!
We’ve just switched on non-geographic numbers (those ones starting 0845, 0844, 0870, 09xx, 118, etc.).
You can enable them in-app under your SIM settings (Account Tab -> tap on a SIM card -> Settings). You’ll need a minimum £5 cash balance to switch them on.
The numbers are made up of a service charge set by the organisation you’re calling and an access charge of 5p/min set by us.
The reason for not enabling them until now is because we don’t get the official charges for these numbers for several days by which point it might be too late, i.e. potential bill-shock, which we want to avoid.
Now, we’ve added the 12,000+ number variants and 100 charge bands into our billing system so we can calculate what they cost immediately, and you’ll see the cost in-app within a few minutes like every other call.
And because we know what they cost, we’ve made a handy search/calculator:
Note: we don’t (yet?) validate the number you search for, so whether it actually exists is TBC. 
Nerd alert
You can search for these numbers via our API as well: https://api.zevvle.com/ngn/{ number to search for }. You don’t need to be authenticated, and I’ll add that to our documentation shortly…
If we find Vodafone using this for their billing I’m going to be mad.
Updated Terms & Conditions
Finally, we’ve updated our Ts&Cs mentioning that you’ll need a £5 cash balance to enable non-geographic numbers, as well as clarifying what happens when you run out of data, go into a negative balance or run out of credit on one of our older pay-as-you-go plans.
In short, if you run out of data we turn the data off — you’ll be notified before that happens, and you can avoid that completely by selecting an automatic add-on (or auto top-up if you’re on pay-as-you-go). If you have unlimited calls & texts, you can still use those.
The updated version 1.2 terms are here.
Have a great week,
Nick
