Are you confused as where to insert the SIM in iPhone 4? Apple iPhone 4 uses a Micro SIM which is 15 mm × 12 mm in size while the standard Mini SIM is 25 mm × 15 mm in size. To insert a SIM in iPhone 4, follow the steps below:
1. Take a simple paper clip and make it straight.
2. Check the right side of your iPhone 4 to locate the SIM tray as shown below:

3. Insert the pin into the small hole and push it slightly until the tray pops-out. Now pull out the Sim card tray with your hands.

Watch the video below (By MyRandomReviews):
4. Place your Micro SIM card into the SIM tray. Make sure it fits perfectly and the golden circuit side of SIM is faced downwards.
5. Push the tray back into slot in the same manner you ejected it out. You’ll hear a click upon successfully placing the tray in its place.
6. Wait for iPhone to recognize the SIM card. That’s it!
Update: SIM insertion method is exactly same for iPhone 4 and iPhone 4S.

Super! That was really handy! Thanks!
i tried the paper clip, didnt work!!! now what?
us a nappy pin
where from we get micro sim card in india?????????
I think currently no carrier in India is providing Micro SIM. You can chop down your normal SIM to micro Sim either manually or buy a SIM cutter from http://www.cutmysim.com/ or from ebay.in (http://bit.ly/crXLsd , http://bit.ly/9ZBE6C)
In delhi u can get it in gafar or cp verry easily
My local phone shop cut all but the gold pins (basically in half) for free & it works fine.
thanks.
Works like a charm!!
Nice work!
Why do I get a normal simcard with my phone?! Damn phone shop!
Thanks for stopping me before I wrecked my new phone!
Very good instructions which I just used. Thanks!

wat your phone number….i need a sim card 4 my iphone4
thanx you
Let me know is it possible to put ordinary sim( Indian make) card in I phone-4?
If you don’t have a micro-sim, you can cut a regular sim card to make one. Search the internet for tutorials on how to do so
how do i gt sim in my phone arrrrrrrrrrrrgh
Brilliant, thanks for that but why dont they show how to in any of the instructions it came with ?!!?
Great ! Really helpful. thanks
I got the chip in, and the phone still isn’t doing anything. What?
They should include the right pin in the box. A paperless solution for the world eh? Why this hell do you need a paper-clip then? The ones that are used for securing more than one piece of PAPER together…the ones that are not digital technology, but common household office supplies.
And why does it matter what size paper clip…Steve Jobs needs to get a job.
This phone is great, but the fact that the SIM card requires a “SIM ejecting tool” is just awe-inspiring idiocy.

just go to any phone shop and ask them to chop the sim in 15mmx12mm
your normal sim would be of size 25mmx15mm

For all the people saying the paperclip doesnt work, I just had the same problem. you basically have to push it in so hard it feels like youre going to break something but it will pop out. its supid i didnt have a key inside my box with my new 4s. crappy. and apple is getting on my last nerve with all this.
dear freinds the iphone 4 is a good handset but his simcard is very bad becoz in india dont get the micro simcard therefore we cut the sim card for our hands therefor this mobile is very bad mobile in india
cheers!
Oh my god. I’m a technology noob… And I used a toothpick to open the thing, but the toothpick broke and now it’s stuck in there! Please! Anyone know how I can fix this without going to the apple store? Please help me >_<
FYI a pin for doing this is included in the iphone 4 packaging, it’s under the parcel with your ‘manual’ and essential apple stickers.
Didn’t work. These instructions are not sufficient. I had to make too many adjustments for it NOT TO WORK. but thanks anyway.
