How does sms gateway work?

Question

SMS

Good day. I want to create an SMS gateway, the gateway should work throughout the Republic. But I don't know anything about this. I would like to know how the SMS gateway works? what equipment is needed for this? where can i buy this equipment? what price will it cost me? As much information as possible. Thanks in advance.

Answer 1

A simple option: usb modem + SIM card + software. One SMS is sent 4-7 seconds. If you have a larger flow, you will need more professional equipment.

Answer 2

You can buy android phones. Sim cards. Choose the best SMS rate.
The phone is usually quite simple. up to 2000-3000 rubles per piece.
On the phone, put an apk from some sort of SMS gateway. For example, SMS gateway SmsGateWay24 or Semisms. I myself used both - I liked SmsGateWay24 more - support is better and the site is nicer, but then who cares.
it is better to take several phones at once and 3 times more sims. since the operator can lock them if the SMS mailing is large. So SIM cards are a consumable item.
Then you throw the customer base into the service. and do the mailing.
It's all about the clients. if there are customers who are ready to order the newsletter, then it will work.
resulting in expenses
one-time: to phones, Wi-Fi router.
permanent: SIM cards, tariff payment. Internet..
