Good company. I'm looking at all these reviews and wondering if these people even used the service? If I'm honest. I have used Zadarma for 6 years. They are good - customer service always answers when I call to resolve setup issues etc. Nice and cheap and I can get as many numbers as I need for my business

travel a lot for work and was sick of swapping local sims all the time. got the time. got the zadarma esim plus a couple virtual numbers and its been genuinely useful. calls stay clear, recording kicks in when i need it, manage most stuff from the app. not perfect, app lagged once or twice, but for the price and the flexibility hard to moan. 4.5 from me

grabbed a couple virtual numbers for the side project last month. set up in like five mins, calls come through clear enough, recording just works. crm bit was a bit annoying at first but once it clicked its been fine. 5 stars

I use this service for corporate telephony, and it’s very convenient. Everything is kept in one place, and there are plenty of automation options. I used n8n for my automations, and everything worked perfectly. I honestly can’t think of anything that’s missing or anything I’m unhappy with. I’ve also contacted customer support a couple of times. They handled everything quite quickly and provided helpful guidance within 3–4 minutes.
