**I. Introduction**
Hello everyone, last week I was hanging out with Aunt Zhang and came across a free offer for a 3-yuan unlimited data SIM card. I immediately applied for it.
After filling in the necessary information online, the SIM card was delivered to my address in Nanjing Shunfeng the same day. The delivery was super fast.
▲ I chose the 3-yuan unlimited data plan without any additional charges. Plus, they sent me a 100-yuan bill. That’s like getting a month of free usage. If you want to know more about the specific pricing, you can check out the article written by @Shen Shao Neo.
The card arrived, but there was another issue: this is a China Telecom 4G SIM card, and my OnePlus 3T only supports one active telecom card at a time. Since I already have a 199-yuan monthly package on my dual-SIM phone, using two telecom cards isn’t possible. So I had to think of an alternative solution.
While browsing, I stumbled upon the Purple Rice MF885 portable WiFi device, which also has a 10000mAh power bank and QC2.0 fast charging support. I thought it was a great find.
â–² I used a 15-yuan discount coupon from Jingdong and a gold coin exchange for an e-card, so I ended up paying just 158.5 yuan.
**II. Unboxing**
â–² The packaging is very simple, following Xiaomi's eco-chain style with kraft paper design.
â–² It supports 4G triple-play service, with China Telecom only supporting 4G, not 2G or 3G. China Mobile and Unicom support 2G, 3G, and 4G. The maximum LTE download speed is 150Mbps. It has a 10000mAh battery with up to 65 hours of standby time. Supports QC2.0 fast charging and bidirectional charging. Can connect up to 8 Wi-Fi users and one USB device.
â–² Front of the box: 4G Netcom, 10000mAh fast charge, and 9 user sharing are all clearly marked.
â–² Inside the box: main unit, manual, and a SIM card slot thimble.
â–² Comparing the Purple Rice MF885 with Xiaomi's power bank, the conversion rate isn't as high as Xiaomi's, but since it's mainly used as a Wi-Fi hotspot, it doesn't matter much.
â–² Size comparison between the Purple Rice MF885 and the Purple Rice Power Bank.
â–² The side has a built-in micro-USB cable for charging the device or Android phones. I found it strange that Xiaomi's newer phones use Type-C, yet this model uses micro-USB.
â–² Removing the side cover reveals the SIM card slot.
â–² The MF885 supports the smallest SIM card size, and comes with a SIM card thimble.
**III. APP Introduction**
â–² After connecting to the Purple Rice MF885's Wi-Fi, you can access the app to manage settings. The main screen shows data usage, remaining battery, Wi-Fi name, and number of connected users. Also, it allows sending and receiving SMS through the app.
â–² In the settings, you can configure traffic packages, set alerts, manage Wi-Fi passwords, and even update the firmware via OTA.
â–² There are also router status updates shown in the notification bar.
**IV. Speed Test**
This 3-yuan unlimited data SIM is for China Telecom 4G. Note that the MF885 only supports 4G, not 2G or 3G. Therefore, if you're in an area without 4G coverage, it won't work.
â–² 360 speed test showed a max of 2.66MB/s.
â–² Thunder download speed reached up to 3MB/s.
**V. Battery Capacity & QC2.0 Fast Charge Test**
The MF885 supports QC2.0 protocol, with input: 5V 2A, 9V/12V 18W; output: 5.1V 2.4A, 9V/12V 15W max.
â–² Even when the power bank is fully drained, the Wi-Fi can still be used for a while. So the actual capacity is around 7877mAh.
▲ Using an Anker QC2.0 charger and a Xiaomi power bank, I couldn’t activate the 12V mode—only 9V worked.
â–² The output can reach the rated maximum of 15W.
**VI. Summary**
The MF885 serves as both a mobile Wi-Fi hotspot and a QC2.0 bidirectional fast-charging power bank. It's a perfect companion for those using unlimited data SIM cards while traveling.
FRP Pultruded Grating, commonly known as GRP Pultruded grating, is made of glass fiber reinforced polyester resin similar to FRP molded grating and features I or T bars as bearing bars with round or shaped bars for connecting rods, which are then assembled into place using certain processes. When compared with FRP Molded grating it offers higher load bearing capacities with improved strength to weight ratio - ideal for installations where exceptional loading bearing needs and uninterrupted spans need bridging simultaneously.
