When the aunt was not so diligent, the child's aunt bought a 360 children's watch for my son. In order to let the youngsters come to interact with my son during the summer vacation, they were deposed and played by the child at the time, so they did not send out of the box, but the wife After inserting the school news card (the shearing Nano SIM card), it can't be taken out anymore. Because the inaccurate size is stuck inside, it's not going to play well. Unprocessed ....PS, here I have to say that under the 360 ​​children watch I think the biggest drawback is that you can not specify the numbers allowed to receive text messages


At the beginning of this month, China Unicom had two NFC calls with a one-year validity period of 550 yuan, a 1500-minute call + 6G traffic (3G national + 3G province) + 50 SMS 4G cards, no roaming free, native Nano, so plan to put the original home 5 The 4G shared package (4G national traffic + 2000 minutes) card is added to the two card daughter cards (6 yuan per month), so that there are 7 cards to share 3000 minutes of phone +12G traffic +100 SMS However, the monthly fee has been reduced (the original 129 yuan +24 yuan, now 92 +30 yuan).

Therefore, it is necessary to change the card inside the watch. The process of removing the watch and taking out the SIM card is very simple and we share:

1. Cut out the size of the card cutter and the edges are slightly tilted so that the plug does not come out....

2, disassemble tools, not to see Zhang Aunt recommended to buy, but often see Aunt broke after buying:

13, the hole above the line has been exposed to the head is large enough to directly pull out the card by hand:

14, ready to insert the new Nano Unicom 128K 4G card (although this watch should only 2G seems):

15. After the standard nano card is inserted, it can be easily popped out by pressing it yourself.

16, put it back, boot, all goes well, that is, 2G Unicom card signal looks like better than mobile, can not see the network information does not know whether 2G or Unicom 3,4G online, the signal often 1,2 grid ...:

17, to remind under this smart watch bracelet bluetooth headset, because the battery capacity is small, and the volume limit over-current protection is also general, it is recommended that the condition is best to charge the computer USB port or specifically get a 5V 500-800ma charging head, try not to plug in the 5V 2A/2.4A charging head to prevent the battery hanging

18, the last Tucao Lao Zhou this children's watch should rely on selling the strap to make money .... two children are two straps are broken
