What programming languages does Bandwidth provide SDKs for?

Does Telnyx have a free tier?

Telnyx does not offer a free monthly plan. It runs on a pay-as-you-go model where you fund a balance and pay for actual usage, with trial credit available for initial testing. Qualified startups can apply to the Telnyx Startups Program for up to $10,000 in credit.

Can I use Bandwidth and Telnyx together?

Yes. Many teams route different message types through different providers or fail over between them. Courier lets you send through both behind a single API and switch providers without changing your code.
