The linker does not call back. What's going on here?

Maybe there is something wrong with their server temporarily. Let's see if it's ok during the day and see if official website has informed us. Besides, tell me what I think. The choice of VoIP depends on where you plan to use it first.

Ali tong recommended for computer phones. For details, please search ali tong Internet Phone Help Center-How to help.

For mobile phones, it is recommended to use Huiyoutong. You can search Hui Youtong's mobile phone page and call back.

Compared with ali tong, Huiyoutong is more professional in dialing back, but the effect of using computer to make mobile phone calls is not as good as that of ali tong. Please compare it.

This is my personal experience. If both computers and mobile phones are needed, ali tong will give priority, but it will not provide free trial, and friends will provide it.

However, it is better to recharge 10 yuan for the first time, and then choose a suitable package after seeing satisfactory results. Try to use online banking, Alipay or Tenpay when recharging. Don't buy a recharge card, I was cheated on Taobao!
