Moving from Telnyx to SMS Mobile App
Telnyx bills a per-part rate plus the carrier's fee, for software built on its API. SMS Mobile App is for people who are not building software.
What stays behind
Your API integration and inbound messages stay behind, and foreign destinations stay on Telnyx. Recipients will see your SIM's number instead.
Steps
- Put your list in a CSV file. Use whatever already holds the numbers, then follow Prepare a CSV recipient file.
- Check the numbers against what we accept. Only ordinary Pakistani mobile numbers in the
030–036ranges go through. Everything else is refused with the reason, and there is no override. - Install the app on the phone that will send. It is a signed APK, not a Google Play app: Install the Android app, and compare the SHA-256 before you open the file.
- Sign in and register that phone. Sign in with Google, register the phone, then grant its Android permissions.
- Create a small job first. Create a job from the CSV with a few numbers of your own, read the review screen, then release it.
- Watch what happens, then send the rest. Monitor the job. A SIM starts at 150 messages a day and at most 30 an hour, so plan a long list across days (limits).
What SMS Mobile App will not do
- Pakistani mobile numbers only. Foreign numbers, landlines and short codes are refused.
- Each SIM has daily and hourly caps. A SIM starts at 150 messages a day and can rise to 400 as delivery reports come back. Its hourly cap is a fifth of that, and a job waits at least 30 seconds between sends. The Free plan stops at 100 messages a month.
- No HTTP API. Other software cannot send through it, so OTP codes and automated sends from your own system are not available.
- Your SIM and carrier decide the rest. Whether a message arrives depends on them, and their SMS rate is yours to pay on top of any plan.
