FAQ
All connection credentials — SIP login, password, and server address — are available in your personal account after registration and account activation. They work with any popular softphone (Zoiper, MicroSIP, Linphone, etc.), as well as desktop IP phones and cloud PBX. If you need help configuring a specific app, our support team will walk you through the steps and send you a ready-made guide.
Requirements depend on the country and number type. For most destinations, a company name and contact details are sufficient; for some countries, regulators require proof of address or business registration documents. Before ordering, your account manager will provide the exact list for your chosen country.
Numbers are activated within a few hours after payment. If document verification is required for a country or the number is ordered for a specific city, the timeframe is 1 to 3 business days. Your manager will confirm the exact timeline when you submit your request.
We accept bank transfers, card payments, and cryptocurrency (USDT and other popular assets).
Yes, in most countries numbers tied to a specific city or region are available — this helps build local presence and increase answer rates. Availability depends on the location you need: tell your manager the city you want, and we'll find a number or suggest the nearest alternative.
