Nowadays, many elderly people use smartphones. Smartphones have large screens and large fonts, which are convenient for them to use. However, they do not know how to turn off data traffic, so they incur traffic charges of up to 100 yuan each month. As children, we cannot bear to blame them, so we have to pay for them silently. Recently, China Mobile launched a nationwide unlimited data package, with a minimum of 98 yuan/month. So I went to apply for an unlimited data package and applied for two secondary cards for the elderly, which solved the problem of the elderly accidentally incurring high data charges. I encountered some problems during the application process, and I hope it will be helpful to everyone. Trap 1 If you think unlimited traffic really means unlimited traffic, then you are too stupid and naive. The package only shows 100G, and the high-speed traffic is only 20G. When the cumulative traffic in the package reaches 20G, the network speed immediately drops below 1Mbps. When 100G is used, the network speed drops to 128Kbps, and the traffic cannot be carried forward.
Trap 2 The secondary card needs to be charged for sharing data, which is 10 yuan per secondary card. If you open two secondary cards, you will have to pay 20 yuan for the function. There is no need to activate the sharing fee in any advertisement, mobile client or during the application process. I only received a text message reminder after I activated it . I am really speechless. Trap 3 If the main card is in arrears, the secondary card will be immediately shut down, and all fees incurred by the secondary card will be deducted from the main card, even if the secondary card has a balance. In other words, if you owe money, you must pay it through the main card, and it is useless to pay with the secondary card. If you don't know, recharge the secondary card, it will be in vain. There should be few people who can cash out from their phone bills, right? A meat bun thrown at a dog will never come back.
