Partners, which company in Hefei do you recommend as an enterprise short message platform and 400 telephone?

Hefei doesn't know much about it, but the SMS platform has no geographical restrictions. If they are not close to you, theirs will be more reliable and faster. Their resources are likely to come from other regions, and they can also apply for a refund if the SMS is not effective. If you are not clear, you can communicate with Babu further, hoping to help you.
