How to make a micro SIM card 

2 things Instead of measuring 12x15mm you could also lay the micro on top and trace it. Also, if careful enough, one could simply cut the micro out of the macro card and the remaining border could be used as the micro-sim adapter.

This guy makes it looks really difficult - no need to do all that measuring, you don't need a ruler or a scalpel - just cut the plastic away with scissors so the chip card fits into the micro sim slot - worked for me!!

Dude, thanks a lot I'm gonna watch this a few more times to be sure how to do the process correctly

had pay as you go sim and needed to make emergency call, thanks did coversion in 5 mins , life saver

It doesn't matter what operating system your phone runs, it'll take any sort of SIM card, you just need to be sure you have the correct sized SIM card for the job. The iPhone 5 uses the smallest size called a nanoSIM, most of the latest smartphones use the slightly larger microSIM card size and older and more affordable handsets use miniSIMs.

Yes, although it's advised that you place it in a microSIM to miniSIM adapter so that it doesn't move around within the SIM tray.

Wow, that was a lot easier to do than I thought. Template worked like a charm!

This video is kinda soothing for some reason..

Why did you use the ruler, for further measurements and cutting, when you already had the micro sim template to hand. Confusing.

Thank you for telling the dimension of the miroSIM. Could you also tell how much to cut off each side of a regular SIM? I have watched several how-to vids since Chrismas and your instructions are the closest I come to getting the info I need.

awesome tutorial!!! i wasted so many sim cards before i got here..

awesome, you must be a professional sim card cutter ! *respect*

It's a useful video. However, I would advice, mark the lines along with the template over the SIM, could give you an exact guide to cut the SIM in a better way. Because after you cut two sides we lost the template lines..... ;) Cool...!!

I dont know about other country, but in Malaysia, go to your network provider & they will cut your SIM card for u, FREE. just a few minutes time, no need to wait for replacement, SIM card cutter r really common now.

Yes but, will the Micro SIM card work at the port for a standard SIM, when you need to change the phone? (for any reason)

Well thanks. I did it directly without talking print out, just looking at the spaces in the video. It works. Thanks!

I watched 46s of your video, then cut mine by eye absolutely perfect...who needs a ruler...

Great video. I followed the measurements of both sides and it works. Just make sure to cut the corner also or it will not work.

I was so crush when i found out that i need a micro sim card for my new nexus 4! I was very reluctant on trying this method but I did! it took me over 40 minutes lol but its soo worth it hahah!

i don't need any other help from you in anything but i like your voice and you sound relaxed so i'll just sub

dude thank you so much. I was in a panic mode but now im ok.

OMG I almost freaked out because I cut it and it didn't work until I found out I put it in upside down ;))

thanks for the guide, it doesn't look pretty but it works! saved myself like $3 and pointless contact swapping :)

Ok fine.. now tell me how to put this cutted sim back in to the normal sim phone ?

This will not work with older 1st Generation Issue Mini SIM cards as the gold foil contact sheet covering the chip is much larger than what is being used nowadays.

You can print out a scale template of a microSIM card from images online as an alternative if you don't have an actually microSIM card to refer to. Good luck!

Good job! I just follow the step from the tutorial and I make it!

I did the same thing with gardening-scissors and it works perfectly!

Excellent video. Clear, accurate, spot on. Ta mate.

Thanks mate, it worked :3 but first i was worried because i had to cut ALL the plastic from both sides, but it does still work :) Thanks again! :D

Are scissors not ideal because they pinch and flex the plastic?

Go to your ISP office and trade SIM cards. Mobily and STC do not charge anything and they have many offices (Saudi Arabia). I did the same with AT&T in USA.

Thank you.This video is very helpful.

Thanks man used a pen, ruler, and scissors and works fine

well, in Bulgaria where am I, my operator wants 10 Euro just because i didn't bought the phone from them .... so big thanks mate !

Omg I was in shock when it worked!!!!! :D thanku!!!

Thanks, appreciate the help, right away can use my new phone.

Very helpful, thank you.

Ty.man a lot! if i waouldn`t find ur video,i`v almost have to give up my s3 xD ty ty ty !!!!

what if i dont have another micro sim to compare? :(

make sure you sand the edges (on carpet if you do not have a sandpaper) else it may get stuck in the slot due to rough edges. in fact you can do the whole cutting part on carpet much faster, smoother and cleaner looking sim.

Does the placement of the sim card affect the signal?? Because I cut mine uneven and I just forced it in there and I only have 2-3 bars at the most

Thanks for this video. You helped me to cut the Tmobile and O2 :D. Both work perfectly :) Many thanks

Nowadays Sim Cards has 3 sizes Nano,Micro,Standard to fit whatever what your phone takes In 2016 mobile network made them more easily to pop out the one you need instead of cutting or making damages that can ruin the sim

NO need for store this is super easy thanks man ^_^

Hopefully this was before tri sim cards came about and it is easier to go from mini sim to micro sim when you have a tri sim card.

Would like to know the answer to this as well. Does T-Mobile provide a micro version of your current SIM card upon request? Does anyone have any experience with this?

Once u change the regular SIM card into a micro SIM card, will it still work in the the other phone that took a regular SIM card?

This was very helpful, thanks a lot

awesome vid - cheers!!! worked a treat :-)

Lol, is that Vaseline machine gun by Leo kottke?

Can it also be used for a galaxy s4?

nice efforts! but what if I don't have a Micro SIM to work with????

i tried this with a rather old sim, which apparently had a chip/dye size the same size as a micro sim itself. yes i did use a micro sim as template so i didnt just cut it too small. but needles to say this resulted in my just ruining my sim. luckily i already have a new one from my new subcribtion, only this one isnt activated yet. guess i'll just have to wait a bit.

Great tip mate...

Does it work for the Galaxy s3?

it is work to my samsung galaxy tab 3 7.0? because i try to insert my sim D: but it doesn't fit D:. should i try your tutorial or not? thank you

nice slide guitar on the background

you can cut the corner first to make it easier

So basically I have already have a micro SIM anyway? Great...

thanks man good vid, very helpful

Great Tutorial

is it new sim technology, or just the new way for the phone makers to get money out of users? we mean is it all new generation of phones etc... our sim cards here U.S.A. we have not noticed a change in size, but we don't have that kind of phone, we have a motorola flip phone, just asking because we may have missed why you need a micro sim.

Nice tutorial, you have to learn how to use a cutter in this tho, because your "scoring" makes the sim very fizzly :P

Thanks for the help :)

i don't have the micro sim template and i'm too afraid to do it myself. i'm so lost , my 8 year old phone just died , and don't have 2nd phone.

I had to get a card from Orange cause the big one in my experia j would not fit my iPhone or galaxy s4 sim cost a tenner and you are quite correct in saying the phone companies just want to rip us off all the time

thank you so much! :)

But how? How do we put this cutted sim card back to ma normal old phone :( coz I use 2 phones at a time.. and I keep switching my 2 sim cards between the 2 phones. ???

If i 've got a micro sim why i ll cut the big one? I 'll put the micro sim.

The sound reverbs so much I can't really understand much of what the speaker is saying.

I had done it man, you can use it in win phone...

i wanna know how to make nano-sim.. for z3

even my microsim doesn't go in the iphone 5 tray ---- why?????

this worked for me thanks !! (galaxy user t-mo network)

With scissors is better but this really worked well.
