Which IOT card is more reliable?

The Sino-Singapore IOT card is not recommended, because first of all, the traffic is not unlimited, but in the form of traffic packets, followed by black-box operation, and the traffic packets are fake.

I used 40g at the end of the first month, 100G at the end of the second month and 200g at the beginning of this month. This traffic is very virtual, and when it is plugged into the ZMI portable router, it is directly bound to the hardware. So it is unrecognizable to take the card out and put it in the mobile phone. Secondly. In the third month, 140g was processed, and the Mizi portable router recorded 70g and then disconnected. 200g this month and then the router traffic record is 40g, and the network is disconnected. The after-sales service is poor, so I just want you to make up the money. They are all agents. They have no power. Recommend ice cream and the like, unlimited flow, and get two more cards. Solve the problem of portable router. The above is for personal use. The official account of WeChat WeChat is a Sino-Singapore IOT card. Not recommended to everyone. It's very pit.

My account number is in the screenshot. You can check it on the official WeChat account. There are also recharge records.
