Which voice provider should you choose?
Two things decide a carrier: can you buy a number where you are, and what do the minutes cost. This page answers both for Telnyx, Twilio, Plivo and Vonage in your country, side by side, at their published rates. It picks no winner. Choose what works for you, and WhautoVoice runs on top of whichever one you connect, for the same flat fee.
Your month
Pick a country and the shape of your calling. The four carriers are priced from their published rate cards for that country.
Set a line to zero if you do not use it. Where a carrier does not sell a line you use, its month is shown as not priced rather than totalled without it.
| Carrier | Local number to buy | Inbound | Out, landline | Out, mobile | Your month |

Who serves where
Every country we track, and whether each carrier prices inbound calls, outbound to landlines and mobiles, and a local number there. Click a row to compare that country above.
Full means all four core lines are priced. No inbound and similar mean the carrier does not sell that line there. Partial means a rate we have not verified rather than one that does not exist. Published list prices only, never converted between currencies.
How to read the table
Local number to buy is the first thing to check: a carrier that sells no number in your country cannot answer your calls there, whatever its minutes cost. Yes means the carrier lists a local number for sale and the figure is its monthly rental. The three rate columns are the carrier's published price per minute for receiving a call, placing one to a landline and placing one to a mobile. Your month multiplies those by the minutes and numbers you set, in the currency the carrier bills that country in. Nothing is converted and nothing is ranked. A month is only totalled when every line you use has a rate: where one is not sold or not verified the cell says so, because a total with a line missing would read as cheap.
What the table does not weigh: call quality and latency in your region, number porting and regulatory paperwork, volume discounts that all four apply as you grow, and per-use extras such as recording and transcription. Price and number availability are where the four differ most on paper, and they are the parts you can check before you sign up.
A short opinion on each
- Telnyx usually has the lowest list price of the four and a US$1 US number, and its figures here already include the US$0.002 a minute Voice API fee it charges on every call. Newer inventory in some countries.
- Twilio is the one most accounts arrive on: the widest coverage, the deepest number inventory and the most familiar console, at a price that is rarely the lowest.
- Plivo is often the cheapest per minute, particularly outbound, and bills India in rupees. The catch is inbound coverage, which is thinner outside its core markets, and the page flags exactly where.
- Vonage quotes every country in euro and prices outbound by where you call from as well as where it lands. Strong in Europe, and the one to weigh in euro rather than convert.
Why WhautoVoice shows you this
Because the carrier bill is yours, not ours. WhautoVoice is bring-your-own-key: you connect the carrier account you choose, it bills you direct at the rates on this page, and our invoice is a flat platform fee with a monthly allowance of processed minutes and extra minutes at half a cent. We have nothing to gain from steering you to any of the four, and something to gain from you picking the one that fits, because a customer paying the right carrier rate stays.
Frequently asked questions
It depends on the country and on whether your calls are mostly inbound, to landlines or to mobiles. Telnyx and Plivo usually have the lowest per-minute list prices, Twilio has the widest coverage and the most number inventory, and Vonage bills every country in euro. Pick your country and call mix above to see the four priced for the same month.
Because a line you use has no rate for that carrier in that country. "Not sold" means the carrier does not offer it there, most often inbound calling or local numbers. "Not verified" means we have not confirmed a rate, which is a gap in our data rather than in the carrier's service. Either way the month is not totalled, because a total with a line left out would read as cheap. Set that line to zero and the rest is priced.
Because that is the currency the carrier bills that country in. Vonage quotes every country in euro and Plivo quotes India in rupees, and this page never converts: an exchange rate would be the one invented number on a page whose whole point is that every figure is the carrier's own. Weigh a euro total against a dollar one with that in mind.
No. WhautoVoice runs on whichever of the four you connect, and its plan is a flat monthly fee with a set number of processed minutes either way. The carrier bills you direct at the rates on this page with no markup, so only the carrier line changes, which is why the comparison leaves the plan out.

Yes. Each WhautoVoice workspace connects its own carrier, so an agency or a multi-country business can run Telnyx in one market and Plivo in another under one account. Numbers stay on the carrier account you bought them from.
