Which service to use to verify the phone number?

Question

SMS

Good afternoon.
We noticed that on average SMS verification costs 1.2-1.9 rubles. Thus, to verify 100,000 phones, you need 120,000 - 190,000 rubles, which is somehow expensive.
Please advise a service for confirming a phone number via SMS, preferably with the ability to call the number (when the robot calls the phone and says the code).

Answer 1

You look at the price tag for a direct connection to the operator and the desired sender name
. With an indirect connection, the price tag goes from 25 to 6 kopecks Confirmation
service by phone - it's better to look for an operator (s) and raise your asterisk. - the price tag is different. I won’t tell the officials now, the goips have somewhere around 2 cents per minute for mobile Russia
