Show HN: SMS-Scope – test receipt of sms in multiple countries
- nbrempel 10y agoSMS-Scope is a tool I built over the weekend to satisfy a need of mine. I work on a system that needs to successfully send SMS notifications to multiple different countries. I intend on using this tool to verify receipt of messages in other countries as well as to verify that the system can convert between human-readable number formats and the e.164 standard (and still successfully send the message).
- detaro 10y agoInteresting. What's powering it? Do you have phones in those countries, are you using a service like twilio, ...?
- nbrempel 10y agoI'm just using Twilio right now. I was surprised a tool like this didn't already exist (that I could find).
- detaro 10y agoI don't know much about how the phone network works, but my worry would be that you mostly check if your system accepts the country prefix and then how well your SMS provider is connected to Twilio. Is there a meaningful difference in deliverability there/would having numbers from the actual local providers make a difference?
- nbrempel 10y agoAs far as I know, Twilio doesn't distinguish between SMS messages coming from within Twilio and those sent from other networks. If that's true, all messages would still need to go out and traverse the SMS network and leave Twilio's infrastructure before landing on the other side. I think this should provide reliable insights into message success/failure at the network level. It wouldn't show any localized issues like if a cell tower is down, though. All that being said, I haven't done any serious research into how SMS are sent and what the network looks like. Would be an interesting thing to look into!
