Beijing website SMS verification code company which is good?

15 years, working in a startup company. I was making a ordering APP at that time. At that time, I also consulted many SMS companies and finally chose to cooperate with the eight-step SMS company. The price is moderate, and it is not bad from trial to formal cooperation. The speed is usually about 5 seconds.

In addition, the short message platform is not divided into regions, which does not mean that local short message service providers are not good.

Several situations in which the mobile phone cannot receive the verification code:

1, the mobile phone is equipped with interception software.

2. The mobile phone is turned off, there is no signal for the time being, and it is overdue or stopped.

3. You can't receive SP message on the first day of recharging after the mobile phone is in arrears.

4. The user has set a blacklist on the operator side.

5. The mobile phone can't receive short messages of more than 70 words.

6. The mobile phone is used abroad or used overseas.

7. The SMS storage is full.

8. Mobile phone networks and operators have failed in some areas.

9. Number of messages sent.

I hope this helps.
