Which one is for you
Pick Sonetel if
- Fits if you want local numbers in a few countries forwarded to your phone
- Works for small teams that want pay-as-you-go calling with no contract
Look elsewhere if
- Tight if you stay on Basic, because every number and call is charged and the bill follows the countries you pick
- Skip it if you want your business number shown on app calls without paying, as that needs a paid plan and verified identity
- Watch out: SMS is only available on some types of numbers
- Watch out: prices exclude VAT, and the default yearly rates are per user per month
Pick Telnyx if
- Fits if you are a developer who wants to put calling and texting into your own product
- Works for teams that want to pay per minute and per message instead of per seat
Look elsewhere if
- Not for you if you want a phone system with desk phones or a per-user plan, as there is none
- Skip it if you have no developer, because setup needs code
- Watch out: monthly cost depends on volume and destination, with carrier fees and taxes on top
- Watch out: short codes cost $1,000 a month, and 800 numbers need a 12-month term at $40 a month after a $500 fee
- Watch out: Growth and Enterprise are minimum spends of $2,000 and $5,000 a month

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
