4G随身WIFI毕业套餐团购" -> "4G Mobile WiFi Graduation Package Discount

admin

See many MJJ queries about their wireless devices. At present, the graduation formula is MJJ card + Haier full frequency and all network portable Wi-Fi (with battery). At present, the four G series of P 物联网卡 is more stable and has a higher value for money. The 10th 24th before purchase of the MJJ y1 package is 1.9 yuan per 300G. After that, it will be raised to 3.9 yuan per 300G. This card currently ships randomly with either single telecom cards or double cards (compatible with each other), which can be used separately after contacting customer service. There is a limit in terms of service when using a single telecom card. Currently, the signal strength near the site is -63 dBm. The speed is still okay for web browsing and downloading. The speed will drop if you use the 20M-40M limited bandwidth when connecting to a distant site. If you buy the MJJ y1 dual card system, the default setting is a telecom card. The device recommended is the Haier full frequency all network portable Wi-Fi (with battery) currently, but most have been cut versions through PDD. I bought a batch of them months ago via coupon and am waiting for them to come back. As for the price, the cost-effective MJJ card is 1.9 yuan plus the Haier portable Wi-Fi device. You need to pay me 100 yuan after I transplant the device and test it. Then, I will send you the payment once I finish testing it. For the MJJ card that was sold out recently, you need to contact the customer service and change your account number before paying the balance. The MJJ card is not allowed to download PT, so you should ignore this post if you're sensitive to this. For those who enjoy DIY, here's an image.
