Many friends will ask me in the background, can I buy the iPhone 15 Pro Pro Max with a lock (carrier lock) in the United States? It just so happened that Guozi spent more than 4,000 some time ago to buy an American version of the iPhone 15 Pro with a lock, and the current American version of the iPhone 15 Pro with a lock starts at about 4,000 points, although it is more than 3,000 cheaper than the Bank of China, which is indeed very attractive. But don't touch the iphone15 card machine!
First of all, we need to understand what a locked machine is. To put it simply, the network is locked, only the network of a specific operator is supported, and it needs to be unlocked in a special way to use it normally, such as card stickers or black solutions, and different unlocking methods will be selected according to different models, as for the effect after unlocking, it often depends on luck. These machines are often attractive, and their performance and quality are not bad, and they have once become the favorite of fruit fans who pursue cost-effectiveness. However, the biggest problem with a locked phone is that you need to crack the carrier lock.
Since the iPhone 14 series, the American version of the iPhone has no physical card slot, and if you want to use it in China, the mainstream solution is to punch holes in the frame, move the motherboard, and install the card slot.
When it comes to the iPhone 15 series, the two basic flagships are the same as the iPhone 14 series, and the difficulty of changing the card is not difficult, and the basic application plan is basically applied; iPhone 15 Pro and 15 Pro Max are uncomfortable, due to the internal structure of the iPhone15Pro series motherboard, so the card change into the plan, it is also a hundred flowers, and because of the special structure of the internal motherboard, so there is no perfect card change plan this year, after all, where the beans are bigger, how can you not change the three-bedroom and one living room!
At present, there are card modification schemes available on the market, I will take stock here, analyze the advantages and disadvantages, and everyone will know why you can't buy it.
1.Built-in SIM card scheme: This needs to take out the motherboard, fly the wire on the back, polish the SIM card and then stuff it in, the cost of this card change is relatively low, as long as about 200 at present, but if you want to change the card or shoot, it is very inconvenient, unless you are an enthusiast, it is not recommended to buy.
2.Ultra-thin card slot: The advantage of ultra-thin is that you have the option of flexibly switching mobile phone cards with less damage, the disadvantage is that you need to polish the inner wall of the back shell a little thinner to make room for the card slot, and cut off the millimeter wave, the waterproof is gone, and there will be a probability of a top screen in the later stage.
3.Special-shaped cells: a relatively new card modification scheme, the number is relatively small. This requires a change to a special-shaped battery, freeing up the position of the card slot, and allowing for free insertion of dual cards. The disadvantage is that the battery capacity will lose about 800-1000mha, which means that the battery efficiency of the new iPhone15Pro ProMax you buy is only about 75%, can you accept this battery life?
4.db box:The biggest advantage of this program is that it does not damage the internal structure,It means that you regret it,There is really a better plan in the later stage,You can change it again,And it supports dual cards,You can change the card freely,And this box is connected to the mobile phone stably,And the battery life is very good,There is no problem with fifteen days of normal use。 Although this scheme says that you can change the card at will, it is very inconvenient to take the card.
5.Shell contacts: The principle of this solution is to add contacts to the side bezel of the mobile phone, and connect the "shell" through the contacts. The mobile phone card is integrated on the fruit shell, and the network and call functions are realized through contact connection. This solution is less harmful to the mobile phone and does not need to hurt the motherboard. But the disadvantage is that the phone case is not replaceable, only supports a single card, and it is said that the phone case may also rust.
Although there are many medium-sized schemes that can change the card, no matter how the card change scheme is not very stable. And the American version of the iPhone 15 Pro series also has a lot of shortcomings:
1.Standby is not good, it can lose power by 20% to 30% overnight, if the background is turned off, it will be better;
2.The mobile phone signal is very different, from the router room to the room without the router room, although it is also connected to the wireless, but the web page cannot be opened;
The most important thing for users is battery life and signal, although the National Bank iPhone also has such shortcomings, but it is still much stronger than the American version, which is why I strongly do not recommend you to buy the iPhone 15 Pro The American version has a locked phone.
If you really want to save that money, I recommend that you go for the iPhone 15 Pro series. The risk is too great to be worth it. You can consider an older iPhone, or use it as a game console. As for the iPhone 15 standard version and plus standard version, the card change scheme is more mature and can be considered.
