At present, the iPhone card machine 14/Plus、14Pro/Max、15/Plus series are changed to dual SIM by default,15Pro/Max market is mainly built-in single card or single card ultra-thin card slot,Here digital donburi has always recommended that novice users first start with a small white card (or eSIM)+phone card,This single card QPE mode to start using,After you have a good understanding, you can start using dual cards。
The card sticker machine is not recommended to use the dual card directly, there are three main reasons, one of which is that the installation of the dual card is more difficult, many novice users in the absence of grinding the mobile phone SIM card, plug and unplug at least one card sticker, basically complete the debugging once need to abolish 1~3 cards, depending on personal ability, some of the cards sent are tossed or not successfully debugged.
The second is the difficulty of debugging, the debugging process of the dual card needs to unlock a card TMSI first, and then insert a card and card into the card to do QPE unlocking, unfamiliar can first unlock a separate TMSI, and then unlock a separate QPE, and then put it together, the whole result process is still a challenge for novices, and it takes about 10 minutes for the old driver of digital donburi. Of course, if it is a single card, the whole process with automatic card is very simple, and you can insert the card and use it.
Finally, it is a problem of the use process, you must know that TMSI unlocking is unstable, we have dual SIM and then unstable areas TMSI unlocked that mobile phone card is easy to jump activation or no service, novice users will be directly blinded for sudden jump activation, if it is 14/Plus, 14Pro/Max, 15/Plus series can directly pull out the card tray, and for the 15 series built-in dual card users are in jail. Huaqiangbei iPhone15Pro/Max series has a built-in SIM card, what should I do if the card does not pop up due to incorrect operation?
There are some users will directly mail the double card over, the digital rice bowl directly helps to unlock it and then send it back, at least 5 times of after-sales guidance in the later use process, each time about half an hour, the customer feels annoyed, the digital rice bowl also feels troublesome, the customer chose a single card + small white card program, half a year has passed, and there is no longer a digital rice bowl after-sales.
Finally, to sum up, if you are not an old user of the card sticker machine, just listen to the persuasion of the digital donburi, honestly use a single card, and then use a double card after being familiar with unlocking, of course, if you have to choose a double card, it is recommended to prepare a few more cards, you must be careful when inserting and unplugging the card tray, after all, it is not the original card slot, and when you take out the card tray, you can slightly lift the card tray up to the screen direction and take it out at the same time (hard pulling and inserting will damage the card sticker, and also damage the card slot).
