Summary: You can buy the Internet of Things card through the operator. If the quantity is large, you can try it. If there are three cards and five cards, then forget it. For beginners, I recommend buying from Alibaba Cloud, because there are a series of cloud operations that can be solved in one stop on Alibaba Cloud.
Use hardware: HAAS600
Proceed as follows:
1. Enter the "Internet of Things Wireless Connection Service" of Alibaba Cloud and select the package. For example, if you buy two China Mobile's Internet of Things cards, the one-month test version (enough for us to experiment) is only 2 yuan 4, and free shipping!
2. Pay
3. Fill in the delivery address
4. Waiting for the express, the delivery is a small envelope with two China Mobile IoT cards inside, which are the same in appearance and size as ordinary mobile phone cards.
5. Enter Alibaba Cloud's Internet of Things connection service console by searching keywords. After entering, you can see that you have bought 2 Internet of Things cards.
6. In the IoT card management, you can see that it is not activated
7. View details
8. To use this card, you need a real-name system
9. Use "Mobile Taobao" to scan the QR code in the help file
10. The screen of the mobile phone is like this: IMEI needs to be found on the device, and ICCID needs to be found on the SIM card you bought.
11.Check IMEI from the device
12. Check the ICCID from the card
13. Continue to fill in on the phone
14. It is found that IMEI does not exist. Why does this happen? This is because although the IMEI has been given to the device when it leaves the factory, this IMEI has not been entered into the Alibaba Cloud system. It is necessary for current developers to manually fill in the IME in their own projects.
15. Fill in IMEI, or in the Internet of Things wireless connection service, select device management and upload the device number.
16. Upload the device number. The method is to download the template, modify it, and upload it. The downloaded version is a compressed package, and there is an IMEISample file after decompression.
17. Edit the IMEISample file. If uploading is only for one device, only one IMEI number is enough.
18.Parse the file
19. The screen after the analysis is completed is as shown below.
20. Go back to the mobile phone Taobao to set up, this time you can bind successfully.
21. Authentication ID card. After the IoT card is bound, it cannot be used yet, and real-name authentication is required.
22. Wait patiently
23. Bind successfully
24. Activation is successful. At this point, the IoT card officially began to serve and provide network functions.
25. Insert the Internet of Things card, you can use the network. The device is successfully online.
Using IoT cards can greatly reduce costs, because IoT cards only provide network and SMS functions, and some cards do not even have SMS functions. So it doesn't need much money in one year.
Using the Alibaba Cloud platform for IoT development can also greatly reduce costs. You don't need to purchase servers specifically, you only need to purchase traffic on demand.
