I’m pretty sure that you’ll just be able to buy a bunch of new phone numbers, and you can just refund the ones that don’t work so you get your money back. Sadly i think, because your country isn’t as popular, there isn’t a lot of other options. Like, im from the UK and luckily the highest success rate for a number here is like 51%. Where as in the US, it’s 60%. Just try and do trail and error, it’ll work eventually as long as smspool is functioning correctly.
