淘宝上不插卡的随身WiFi,只要你买的是正规的产品,都是靠谱的。不插卡的原因是因为他将卡集成在了随身WiFi之内,也就是说你只能用某一个电信运营商的产品,而不能更换成其他的运营商的产品。
如果是插卡的话,就是说你如果移动不满意的话,你可以换联通,二者的区别仅在于此。
如果你购买的这家产品运营商是比较靠谱的,而且能够保证长期稳定的运营,买个不打卡的也是可以的。
As long as you buy a regular product, the non-card-insertion portable WiFi on Taobao is reliable. The reason for not inserting a card is that the card is integrated into the portable WiFi, which means that you can only use the product of a certain telecom operator and cannot change to the product of other operators.
If it is a card-insertion, that is, if you are not satisfied with China Mobile, you can switch to China Unicom, and the difference between the two is only this.
If the operator of the product you purchased is more reliable and can guarantee long-term stable operation, it is okay to buy a non-card-insertion one.
The portable WiFi on Taobao is reliable and there is no problem in using it. Electronic products on the market are now very complete, and there is generally no problem with the quality.
Online shopping products are naturally no exception. It is nothing more than the transfer of products from offline to online, and the price is favorable. After buying online, as long as you install it correctly according to the instructions, there is no problem in using it.
The non-card portable WiFi on Taobao actually lacks a telecom card. The telecom card is equivalent to some phone cards with larger capacity, and then the monthly traffic will be recharged a lot, so it is equivalent to a mobile WiFi, but if your signal is not good, the WiFi signal is also relatively weak.
