How to send SMS to users for free?

Question

PHP

Good afternoon. I have phone numbers of users in the database. Is there a free sms service?
How to set it up in php?

Answer 1

In automatic mode, using third-party online services for free. However, for a modest amount of money (for example, 1 kopeck for 1 delivered message), you will be provided with a decent API, and maybe even a PHP SDK to boot. Are you greedy? Then you need to buy your SIM card with an unlimited SMS tariff and connect it to PHP yourself.

Answer 2

You write a small php script that will issue a list of numbers and SMS text for a token, you write a java (j2me) program for a phone that will request numbers and SMS text for a token and send SMS.
You buy or find a nokia java phone (3110c, for example), insert a SIM card into it with a cheap rate for SMS and unlimited Internet (for example, Super MTS - 10 kopecks to any Russian number, I don’t know about the Internet account), copy your java application to phone, select this application in the phone, press the right soft key, then Access > Send SMS > Request. once; Access > Network > Request. once.
Turn on the application, when prompted "Allow an application to access the network", press "Yes", when prompted "Allow an application to send SMS" press "Yes".

Answer 3

There is an interesting solution, I don’t remember the site, unfortunately, but the point is that an application is installed on android, and the mailing goes from your number - which is inserted into the phone, all this works through the site and their api, and you don’t have to pay money to them, there is only a fee for the speed of sending.
Who knows what kind of site - write, I unfortunately already forgot.
