I'd like to ask, how many numbers can you choose for each group of corporate SMS?

Generally, the gateway can select 200,000 numbers at a time, and the problem of delayed receipt of short messages is very common in the field of short message sending. You must send cards, only sending cards is more obvious, and there is also the problem of deduction. Go to their place, and you ordered a short message group, but I advise you not to use short messages cheaply in the future, set cooperation according to the price, find a reputable company that has been texting for a long time, and sign a contract. If you have any questions, you can add me directly, and I will try my best to help you answer them!
