How to cut your SIM card (Micro SIM, Nano SIM - iPhone 5) 

shit had me nervous, like trying to defuse a bomb or something.

I guess you could call this "cutting edge technology"

These instructions were clear and accurate. I followed them and successfully cut down a mini SIM to a nano SIM in a few minutes. I used 180 grit sandpaper to decrease the thickness of the SIM. It was also helpful in doing final adjustment to the width. In the end the new nano SIM fit in the carriage perfectly in all three dimensions. It wasn't as hard as I'd thought. Thanks for the great instructions!

wow first unbox therapy video where the guy is not acting like hes fucking high on cocaine

'No sim card inserted' .. yep! I've fucked it up!

This was surprising simple. I spent way too much time searching round the house for sand paper, tape etc and in the end it was really easy with just the scissors. Worked first time with no sanding. Cheers!

The process was extremely easy! I've already converted a Mini SIM to Micro SIM for an LG G4 and a Mini SIM to Nano SIM for a Samsung Galaxy A7. Thank you very much for your video, it helped a lot. Keep up the good work! I subbed!

Fun little tutorial. I came to learn that i cut my sim card far too much, so the extra tape helped me out in making my simcard still stick and be useable. Worked flawlessly.

I was searching for this and now I bumped into one of Lew's old videos!!!!! :D

I think I fucked up my simcard :'(

Worked perfectly for me. I went from a Note 4 (micro Sim) to Nexus 6P (nano Sim). No problems at all. Thank you for this! I just used Scotch Precision scissors that I got from CVS and worked great. Was very easy to cut.

One of the most useful guides I've ever watched here. Thanks man!

Worked perfectly, thanks for the template and spot on instructions. Also used the sandpaper to smooth the edges to fit in better as well!

Watching this in 2015, trying to install my sim to my New OnePlus 2. Quite helpful, thanks Lue!

Thank you for the well produced video! Just successfully converted a micro SIM to nano SIM for use in a ZTE tablet. Card was already active so this saved me a little bit of $. The key was sanding it down enough to slide into the slot☺

This is Gavinlovesdogs on my Brothers account. So I had a Micro-Sim Flip phone. I got a Nano Sim Phone. I was a bit scared to use my real sim, So I tried it with a in-active sim. I did the steps, (Without a template) and The old Number on the In-Active Sim popped up in the Settings. I was amazed. Thank you so much. Cheers, Gavin

So I bought a 3.8" phone several years ago, which used a mini-SIM. Then I bought a 4.7" phone, and that used a micro-SIM. Now I have a 5.96" phone coming soon, and it needs an even smaller nano-SIM. What's going on? Who keeps wanting to put smaller and smaller SIMs into phones that just get bigger and bigger? In a couple of years, am I going to buy a phone so big that I have to store it in a backpack, and they'll tell me I have to get a new atom-SIM the size of a needlepoint?

took me light years to finally do this, VERY HELPFUL

just wanted to say i followed your instructions AND IT WORKED! i didnt even have to sandpaper the back. my galaxy s9+ tray took the mini sim just like that. in forums everybody kept saying you should never cut the metal part but thats obviously wrong. my mini sim even looked way different from yours, it was oversized on all four sides, but its important to look for those grind marks that your phone leaves on the sim card. thats the important bit. i used one of those mini-micro-nano adapters as a guide. just left the nano part open and put it on top of the mini sim, then drew the nano-sim lines and cut it. again, watch for the marks. thats where your phone connects. A+

Just bought a One Plus 5T and had to cut my micro SIM into a nano SIM. Thanks to your video I was able to do it really quick. Great video! Thanks so much!

back when unbox therapy made useful videos

Man if you're watching this video for no reason in 2021, you're not alone

Totally cut my sim card using your guidelines. Didn't use a template or draw lines as I could tell where I needed to cut it. Did sand it down, popped it in the new device and it totally worked. Had I not seen your video, though, I never would have attempted it. Thanks!!!!

Worked with no problems. Didn't use the template. Had a nano sim to use as the template. Scored the sim with a razor and cut along marks with kitchen knife. Used sandpaper to thin the chip and round the corners. Appreciate the tutorial.

Three years ago this is the video that I first watched that made me sub :) still love the content

I fucked my sim up

Not all cuts shown, bad Sandpaper trick, good Stencil, good Link for alt device, good Subscribed. Thank you for the video.

Great, It works! Few cuts and I have NanoSIM. Thank you! You saved me time and money.

I just used *Norton SandWet Waterproof Super Fine 400 Grit* sandpaper to make my microSIM a nanoSIM. Very quick and painless and I daresay more precise than cutting. This SIM has followed me from phone to phone since it was a regular sized SIM in 2012!

Sitting here in 2021, and looking back, I would not have trusted myself to cut up a SIM card, but I still done it anyways, so much easier to just pop it out of the card today

Thanks for sharing, I was nervous about cutting into the metal portion but watching it be done helped.

Works AWESOME on my new Nexus 6 that Verizon said couldn't be used on their network. I bought it off Ebay brand new still in box from a dealer who had sold over 1000 of these. Just took my old SIM, used your excellent template and instructions, cut it down, and wham, Verizon on the phone they said would not work. Verizon couldn't help, Motorola couldn't help, but you sir, did help me :-)

it's 2019 and i really needed this~ >_< thanks

RIP CARD, I DID IT SO WRONG! FUCK THIS...

Super easy guide to follow, works like a charm, ty!

Thank you very much, took me about 10 minutes and a lot of patience with some little sharp scissors.

Omg I just eyeballed it and it worked. Thank the Lord!!

Worked perfectly for my iphone 6s ^^

I found a copy of the template he used and it worked awesome for me! Thanks man!

Oh my gosh. I didn’t think this was actually going to work! I messed up my cuts and it still worked!

Instructions unclear. I cut my SIM card in half...

I did it with nail clipper :DDD

I needed to cut a little piece of the metal contact, I didn't know that I could do that. Thx a lot! Greetings from France

damn from 2012 to 2018 the difference is real. You deserve the 10 million subs

Omg this guy loves to talk. He didn't take a single breath this whole video

Thank you so much for the tutorial! Worked perfectly. I used a nail file for the sanding instead though. :)

Wow. What a throwback xD I'm about as old rn as Lew was, when this video came out.

I took your advice just to cut it as close to the gold part as I could, without cutting into it, and voila! works like a charm. Didn't bother with the paper, lines, etc. but I did use my kitchen scissors.

Worked great thanks for sharing! :)

October 2019...this is a history lesson in ancient tech problems

Holy shit. I just did it .. I even cut a piece of the gold part off .. and it worked RIGHT AWAY! .. Bought an S7 and had a Micro SIM that I cut into a Nano SIM. Thank you for this!!! Saved me $20

Did this with nothing but a pair of scissors and worked great. Saved me a 3-4 day wait for a copy to be made. Definitely works if you pay attention and do it right.

You're A life saver man. Fuck a 20 dollars

IT WORKED, i feel so smart

THANK YOU SO MUCH LOU THIS HELPED ME SO MUCH KEEP UP THE GREAT WORK MATE LOVE IT

I was like "he sounds like lew" then I looked on the channel and I was subbed and notifications then I saw it was unbox therapy! Wow. Humble beginnings

I didn't need a template or marker I just grabbed my scissors and cut to the metal bit and somehow it worked

got mine cutted , Mini to Micro then to Nano don't need sanding , push slightly harder for it to go in.

Hey thanks man this video really helped me out today I was all worried at first to try it but luckily enough it worked thanks for this video man i owe you

Very helpful when travelling and swapping SIM cards. Thanks for sharing and thumbs up =)

lew sounds like he knows what he's talking about... what happened to him in 5 years

R.I.P my minisim

It worked after a bit of fiddling. Saved the day. Thank you

Articles and this video makes it a lot harder than it really is. I tested the procedure first on an extra micro SIM I had. I didn't use a template or anything. I basically just cut all the sides off as close to the metal edges as possible. Once done, I inserted it into my new phone...and it was detected! I then did the same thing to my own micro SIM and, again, it worked. Neither SIMs I cut even looked that great or anything, but it fits in and it works. Thank goodness too. If it hadn't, I would have lost usage of my phone for several days while a new nano SIM is shipped in.

a world without sims interests me

What's next.... Nano SD card? or perhaps, Pico sim card?

man, youve come a LONG way lou!

October 2018 Lew I try to see all your videos now I have seen the most of them keep going if you saw my comment

"whats up guys, it's lube here..."

hey heyyyy i click on the link and it takes me to a page where the language seems different than english, where do i click to view that template

Thanks. Worked perfectly. It also works if you already have a nano sim card and use to cut into shape.

Works great :) I put it in the wrong way around on the first try so it said I still had no sim, but then I turned it around and it worked immediately :D Thank you for this video

Instructions unclear, i cut my hair like Rihanna.

how do u not lose data on the sim by cutting the metal section

It worked! Thank you!!! I didn't use a template just held it against another nano, but holy crap, thought i'd stuff it up.

Mine worked fine for a new Samsung J5! Thanks a lot. Was really nervous but got it lined up well on the template with a tiiiiiny bit of prestik and them put wide transparent tape over it cause I didn't have double sided. Used a scalpel to make initial guidelines, then pen, and when i cut I gave it a small ~0.7mm bit of excess width on all sides to be safe. Took the last bit of tape off the contact surface, gently neatened the sides with the scalpel to fit the nano bracket and didn't need to sand it thinner.

I have no use for this what so ever, I still watched a 6 min video on it for.. some reason...

These full sized sim cards without cuts are kinda rare

Worked! Excellent! Sanding is the way to go, I only made one cut. All of the rest was done on 600grit paper, probably possible with any paper finer than 250grit.

Didn't even realize this was Unboxtherapy till I looked at the discription!!!!! thought id know Lew's voice anywhere. gotta watch more older vids now!!

you know sim cards can be resized right?😊

Link for template doesn't work?

great video thank you for this. very tempted to do this myself right now but I'll just wait til tomorrow to take a trip to the store so I have both types of sim cards just in case.

worked perfect micro to nano, very very thank you for this tutorial. The only thing i need to do extra after cuten was to sharp the edges after that the top and it works pretty well. no error thank you. sub :)

Who needs a template? Just do it ✅

who else is worried they'll fuck it up if they try ?

Thanks. It worked like a dream. Only 10 minutes effort.

it works!!! thanks man. so easy. i didnt even need the template

Can phone companies provide nano sim for the same phone number for which you had a micro sim? That would save the hassle of all cutting & grinding trial & error shit.

Get a nano sim then get an adapter

I did it without seeing all the video and without listening the sound because I was at work jajajajajajaja. Thanks! :D

Excellent Thanks so much for your excellent tuition,tried for hours to change my card ,not pushing the remove tool in far enough.again thangs.

Wow. $20 for a sim? its like what 99p in the UK (Around 70-80cent

Who's finger was that on the left at 5:27? D=

Great video! Really easy to do and it works great! Thanks

Worked perfect thanks lou!

If you own a 700 $ phone, buy a nano sim card. Don't be that guy

I did everything you said and mine still says no sim 😩

to be honest tought it wouldn't work but actually worked !!!! thank you so muchhh

I was watching this video but I didn't realize that I am watching unbox therapy, you changed so much
