M800 Virtual Numbers review
Global virtual numbers with voice and supported two-way SMS, priced per number.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
M800 Virtual Numbers provides cloud-based local, mobile, toll-free, vanity and international phone numbers for organizations that need to communicate across markets. Businesses can route voice calls and SMS over the internet without physical phone lines, SIM cards or office hardware. The service supports small, mid-market and enterprise organizations, with connection options spanning mobile, desktop, browser, SIP and cloud contact centers. Its reach and variety suit teams expanding internationally or supporting customers in multiple markets; businesses seeking a single domestic line may find the broader offering unnecessary.
Pricing is per number rather than per user. According to the published rates, a USA local number starts at $19 per number per month, while a USA toll-free number is $49 per number per month. Those are monthly number fees, not complete usage costs: calls and SMS are charged separately, and toll-free usage rates may require a quote. Prices vary by country and number type, so the listed USA rates are not a universal price for international numbers. Buyers should account for both number fees and usage when comparing costs across markets.
The main strength is breadth of number choice and geographic availability: numbers are available across more than 200 countries, with Universal International Freephone Numbers offering a single contact number across markets. Calls and SMS route through cloud communications infrastructure, and two-way SMS is available on supported mobile numbers. That makes M800 a fit for businesses coordinating communications across regions and platforms. Support is listed through documentation, so organizations that prioritize other support channels may prefer an alternative. Teams needing straightforward international reach and flexible connections should consider it; those with narrow local needs or a preference for bundled usage costs should compare other services.
