I’ve tried Twilio and MessageBird before. CALLR definitely has the most interesting pricing and the setup is straightforward. I used the Ruby gem and had no issues programmatically sending SMS and setting up a web hook for incoming messages. The team is very responsive which is also a nice advantage. I would definitely use CALLR for my projects in the future.
Très bon produits et équipe très sérieuse et réactive je recommande leurs services.
1/ It works 2/ Possibilities are endless for a programmer 3/ FINALLY someone who does not charge EXTRAVAGANT pricing for calls outside the US.
Prices are competitive for the EMA region and the support is reactive. We've switched from Twilio 8 months ago, we have a much more stable line no! No delivery problem so far and great documentation.
