Heavy news... Heavy news... Bombshell news...
The American version of the iPhone 15 series model was "basic" by Dahua Qiangbei!
A long, long, long time has not been in contact with the so-called American version of the model of the little partner, hearing this news may be confused, the American version of the iPhone 15 series model?
Including Guozi, the last time I bought the US version of the iPhone model was the iPhone X when I was still in college!
Why buy the American version and not the National Bank?
The reason is simple: it's the price advantage!
Think about the price of the National Bank iPhone X at that time of 64GB 8388 yuan, 256GB 9688 yuan, the US version is nearly 1000 to 1500 or so cheaper.
In addition to not enjoying the warranty policy on the mainland side (there is the so-called store warranty)!
In terms of use experience, the US version of the three-network iPhone X bought by Guozi at that time was basically the same as the national bank.
And to the next generation of iPhone Xs begins, the American version of the model! It doesn't seem to be so fragrant...
Although it also has an advantage over BNM in terms of price.
But like Xs Max and Xr, two models that support "dual SIM and dual standby", the US version is a configuration such as "physical single card + virtual single card (eSIM)".
This also means that the US version of Xs Max and XR cannot perfectly support the "physical dual card dual standby" function like the National Bank.
From an experiential point of view, the price is cheap, but it is not always a taste to use.
You must know that the Xs Max and XR generation models, "dual SIM and dual standby" function, but an epic update!
Therefore, many small partners still gritted their teeth and chose the National Bank version model for the "dual card and dual standby" function.
And then everyone also knew, not long after, snapped! Soon...
Huaqiangbei has come up with the unique trick of iPhone XR "lossless change dual card".
Just replace the corresponding single card slot on the motherboard with a double card slot, and you're done!
Not even welding.
This method has been used until later models such as 11, 12, 12 Pro, 12 Pro Max, 13, etc.
As for Xs Max, 11 Pro, 11 Pro Max, 13 Pro, 13 Pro Max, these!
But it can't be replaced without damage.
Because the SIM card slot of these models is soldered to the motherboard.
If you want to change to dual cards, you need to layer the motherboard (because it is a double layer motherboard).
It involves changing lines, removing virtual SIM card chips, soldering or something...
It will be more cumbersome, and it will also test the master's craftsmanship.
What about a good master! It can retain the waterproof function after disassembly and assembly; Live almost it! This dismantling waterproof function is gone.
And to the generation of the iPhone 14 series!
The US version completely removes the physical SIM card and uses eSIM technology instead.
It is also from this generation that the American version of the iPhone is going further and further with us...
Of course! Despite this, this is still difficult for the great gods of "Huaqiangbei".
Although the US version of the iPhone 14 series uses eSIM, the mobile phone motherboard has not changed significantly.
It's just that the card slot is not welded up, and a plastic gasket is used to plug it.
The motherboard still reserves the card slot position!
In this way, only one cable, double card slots, scraped contacts for soldering are almost OK, and there is no need to layer the motherboard.
Then add about 30 pieces to punch holes and grooves in the middle frame...
A basic American version of the iPhone 14 series model, and you're done!
And now the latest generation of iPhone 15 series, it is not so simple.
The standard version of the iPhone 15 and 15 Plus is barely good, and it can basically follow the routine scheme of the previous generation 14 series (the card slot is reserved inside the fuselage).
But on the 15 Pro and 15 Pro Max, it doesn't work.
The first is on the motherboard, according to the comparison chart shared in the blogger @微机分WekiHome video:
It can be seen that the location of the components of the National Bank version and the American version this time is different.
The position of the card slot on the side of the National Bank version, to the US version is the ROM hard disk slot.
This means that unless the motherboard is destructively cut, there is no room inside the fuselage to install the card slot.
You may not have imagined that Apple would adopt two sets of motherboard solutions this time regardless of cost.
In order to solve this problem, the bigwigs of Huaqiangbei thought day and night...
Ultimately! They came up with these solutions:
The first kind!
It is the Douyin @果匠科技 guess that the L-type battery is replaced by a long strip-shaped I-type battery, so as to reserve the card slot and forcibly install.
This kind of scheme sounds like that, and it is more reasonable to blink a glance.
But the problems that come with it are:
First of all, the most significant is that the battery is reduced to 2000mAh (battery life direct drop).
After there is no original battery, it is necessary to customize the type I battery (the quality is not guaranteed, and the cost is increased).
The position of the signal antenna needs to be moved and changed (there may be large loss of signal).
The hole punch position of the card slot is the snap position that holds the screen and the back cover (the integrity of the body is not guaranteed).
The big guy summed it up as:
There is no commercial value, let alone such a solution!
More as a "toy" to play with...
The second!
It is like Douyin @杨长顺维修家, which moves the entire chip kit of the American version to the bottom of the motherboard board of the National Bank, so as to achieve dual SIM dual standby.
Without further ado, this big guy did just that...
Under the effort of dismantling, loading, disassembling, and installing.
The main chip on the US version of the motherboard has finally been emptied!
Only empty plates remain.
Move all the chips to the BOC motherboard...
Then light up and plug in the SIM card for testing!
The base belt came out, and the numbers of the two cards were also read out smoothly.
As long as the subsequent punch holes and grooves in the middle frame of the fuselage, it is basically OK!
Incidentally, the fruit side is: Pro's titanium material is punched in the middle frame, and Huaqiangbei has also been successfully done...
@杨长顺维修家 This plan of the big guy really works!
It's just that this very, very testing master's craftsmanship because:
If you are a little careless in the process of chip disassembly, the machine will be directly scrapped...
So from the perspective of time, energy, and cost, this is still only suitable for their own tricks, and it is not mature!
And if you think about it, you also need motherboard layering, chip transplantation, and need to find the bottom of the empty shell board.
After this machine arrives, do you dare to use it?
The third is more show~
Say it's the best solution at the moment!
According to Douyin @飞扬档口阿姐:
This solution does not need to cut the capacity of the special-shaped battery like the first one to affect the battery life, nor does it need to layer the motherboard like the second one.
Like the National Bank version of the machine, the card will send out the signal!
You never know where to insert the SIM card from...
Surprise ！
Card slot at the top...
Dream back to iPhone 3GS ~
So here's the problem!
How does the card slot open to it?
The fruit above mentioned that the interior of the American version of the iPhone 15 Pro model has no space to accommodate the location of the card slot! Even the motherboard has no vacant slots.
How to do it?
Transform the hardware in the interior space.
How to change it?
According to the fruit: remove the "earpiece speaker" module above to make room for the card slot!
Won't the call and the outside be affected without the handset, the speaker, and the external broadcast?
People thought of it too!
Douyin @深式老卢 specially found a manufacturer to "specially customize" an ultra-thin earpiece speaker...
This is to solve the problem of phone calls and out-of-office calls.
He also said that the effect of the earpiece is basically the same as the original, but the sound will be smaller in terms of external playback.
Emm......
Never mind!
Let's honestly buy a national travel machine~
In fact, to the generation of the 15 series, it is not difficult to see that the American version of the iPhone no longer has any advantages at all, aside from the cheap price, the "new only overhaul" piece, the fruit is not recommended to you.
Because of the machine that has experienced such a "major operation", there is really too much uncertainty~
Although the National Bank machine is expensive, it is backed by multiple guarantees such as official warranty, so at least you don't have to worry about it.
The fruit is to admire a technical master like Huaqiangbei, but it is related to our own use, no matter what the reason, the fruit is 1000000% recommended to buy such a model.
