How to organize automatic testing of a sms mailer?

Question

SMS

Good afternoon!
There is a site that uses sms to confirm orders (regional, 100% sms is sent across the Russian Federation, in the regions).
There is a problem - periodically, sms does not reach the recipients (complaints are received).
I am interested in the opinion of colleagues experienced in this matter regarding the verification of the reliability of the service through which sms mailing is carried out. Are there any successful practices for automatic testing of the service (or services that provide this service).

Answer 1

The problem of SMS delivery is usually related to the SIM card itself. I myself faced such a problem of non-delivery. and for no reason, they simply stopped delivering; Sending from my SIM card. At first I used semysms and it didn't work. then I switched to SmsGateWay24 - figured out the delay between each sms. There is a function - add a dynamic delay between sms. it is also useful that you can track the delivery and forward sms that are 100% not delivered to another phone. And send them already from him. Of course, here you need to use your SIM cards. with their phones. more heroes than through the usual gateways that are sent from their phones - but you can see for yourself what has reached and what has not.
at the expense of automatic testing of deliverability - you can set up a message cart when the SIM card falls.
Since there is an API for incoming and outgoing SMS, for SMS status. and webhooks to my server - I still use smsgetway24.
