How to receive 60000 sms in a week?

Question

Mobile development

Hello!
The question is quite general, so I added a few related tags.
The task is to vote by SMS.
I'm trying to figure out how to painlessly receive 60 thousand SMS per week and add the number / message to the database.
Short numbers and earnings on SMS are not expected!
The questions are:
1) Are there similar services (which, after receiving SMS, send a webhook for example)
2) You can just use several GSM modems, but the question is whether the operator will ban you for this
3) What other options?

Answer 1

any sane sms service offers and receive messages. You can also buy a dedicated number there.

Answer 2

1. Example: https://smsc.ru/api/http/?SE=101c5865#inbox
2. You did not specify the programming language, in any case, you need to interact with the GSM modem, example:
