The iPhone 4 Micro-SIM Situation
June 16, 2010 | Andy Boxall

Because there are now several countries where the iPhone 4 is sold unlocked, everyone can choose the best network and tariff for their needs while not tying themselves down to a long contract. There is no doubt that this is the way phones should be sold, however, buying the iPhone 4 in this way has a distinct problem all of its own: the micro-SIM card.
The person who buys the iPhone 4 unlocked from Apple almost certainly has a phone with a contract already, which they’re presumably happy with and have no wish to change or upgrade. But their existing SIM will be a mini version, used in every digital phone since the late-’90s, which won’t fit, leaving them with two solutions.
Solution one is to attack your SIM with a pair of scissors and cut it down to size. The trouble is, you’ve got to be precise and if you’ve seen a micro and mini SIM together, you’ll know that the chips are slightly different sizes so there is no obvious guide to aid measurements. If you mess it up, you’ll be left without a phone or if your mini-SIM was using all of the chip surface, you could lose data and be without a phone. Some choice.
So, not wanting to slice up your card, you could request a new micro-SIM from your network, but you’ll have to wait for it to be delivered, leaving your brand new phone in the box until it arrives, then activate it over the phone. You could also drop into your local network shop and ask for a replacement there and then, but judging by this report, some customer service staff don’t even know the iPhone 4 takes a different size SIM! So good luck with that.
Worst of all though, is if you’re planning to take your unlocked iPhone to another country and want to use a SIM on a local network, as you’ll have to choose the first solution to the problem unless the iPhone 4 is already sold there.
You can forget about the lack of Flash support and the high prices, the biggest pain about the iPhone 4 is its use of the micro-SIM card, which for many offers no benefit and is only viewed as an inconvenience.
As in all times like this, there are one or two heroes who emerge to assist the frustrated masses. The first is a company called Cut My Sim, who produce a sort of stapler/hole punch hybrid that will cut your existing mini-SIM down to micro-SIM size. A great idea, but it costs $25/£20 and is sold out until July. Then there is a man named John Benson, who has published in-depth instructions on how to cut down your SIM to micro-SIM size. It looks relatively straight-forward, but the meat cleaver may be a pain to find.
Are you in a similar situation? Tell us how you’re planning to get around the micro-SIM situation if you’re buying an unlocked phone. Is your network helping you out? Or do you have another solution we haven’t mentioned here?










The real question is, can an unlocked phone be bought in Canada and used in the US?
Yep that is the million dollar question. And I say yes they will. I’m totally stoked about this too…
Your new iPhone. Direct from Apple and ready to use.
When you purchase your iPhone from the Apple Online Store, you’ll get it commitment-free. So you can sign up for service with the carrier of your choice and change your carrier at any time
So I can buy an iphone at full price, and then pay for service rates that are high, because they were intended to for customers who paid for their iphone at a discounted rate? Maybe I’m missing something here but I don’t see discounted service rates for those who pay full price for thier iphone? Please enlighten me!
@Buck: valid point. At least selling the iPhone 4 unlocked will allow those who are stuck in a contract and are not due for an upgrade to buy an iPhone 4 and swap phones.
@Buck People who have been long time clients can often negotiate with their carrier for better rates. This is the case even more if hay are out of contract and not taking a hardware subsidy. The carrier will offer them discounts to sign the coveted contract.
I gave my provider a call. Orange UK. Said they will order a Micro SIM card for me today and when I get my Iphone call them to register the Micro SIM.
So I think give your provider a call first and see what they say before coughing up £25 or butchering your Mini SIM.
I would not call it “butchering”… I just ordered a micro sim adapter on eBay, it arrived within 3 days (seller is in Europe) and just cut my sim with scissors to the appropriate size given by the adapter. There are some videos on YouTube if you want to see it done as well. All in all: it’s a very easy process.
Hi guys. Just bought my Iphone 4g. However, I am quite shocked that I can't use this microsim card in my Iphone 3G… I've been told the microsim adapter can solve this issue. I've heard http://www.gomicrosim.com has good price and quality and is based in the UK. What do you think, is it worth buing one?
teri ma ka bhosda
chal chup kar kaminey. haha
look on ebay. i have just purchased on for AUS $1.00 plus 45cents postage.
See how and where to get solution at

I got my iPhone 4 today, popped out the micro sim, placed it over my old sim and traced it, cut it close with a scissor, then used a emery board to size it and knock-off the pointed corners, works great.
Also, used the left over cardstock that my old sim card came in and made an adapter so the new micro sim could fit into the full sized sim holder on my old iphone, took a little time but it worked out fine.
SIM card for asean country area…need a solution for this,espciallly for Brunei Darussalam country.Did you plan or schedule to release the iphone4 to this mention above country?….Can't wait for any longer..Hope your iphone4 can WORK with our SIM card and fully function in our region too..Gd luck
Can someone answer this:
If i buy iphone 4 unlocked in the UK.
I then go to New York for a month – can I even purchase a micro-SIM 'pay as you go' style ?
Do they exist ?
Reason is iphone4 sold as contract only with ATT in the States ?
Anyone know ?
not that I know of…I dont think so
Tom, did you find an answer? I'm heading the US with my unlocked iphone soon too, and would really like to know it it's possible.
If you already own the phone they'll give you a pay as you go plan, but you might have to cut the sim yourself.
Hey all…goto an ATT store…ask for a NEW Standard SIM…
Go online to ATT website or call…and activate the sim for pay as you go.
Cut down the sim as stated here in this website and walla…
ATT will try and feed you a line of crap that you cannot have a "pay as you go" account in a smartphone…
I got around that by simply activating the sim without ATT's involvement…by internet and using a credit card to preload it…then select your features and data and you are set to go…I did this with an Aria and it works great…I see no reason it would not work with the Iphone
Guys, there is a way to use microSIM card in every mobile phone, and not only in the Iphone 4 or Ipad! I heard there is a thing called micro sim adapter. Basically, you put your microSIM card inside it and use it in any phone. I googlesearched it and found it here: gomicrosim.com They say it costs 4.5 EUR. They also seem to offer the sticker guide to cut the regular simcard into the microsim. IMHO their price and quality are the best so far.
Just did it with cuticle trimmers and a nail file. Works great. Powered off my phone, stuck it in, powered it up and got an "iPhone activated" message. No problems whatsoever.
Just make sure to not cut any of the metal parts. Best to fit it to the tray on the iPhone 4, as it is a very exact fit.
if the iphone 4 was not a hot product aplle would stick with regular sized sim.
hi i have a question ' any gold color chip can be supported to the Iphone 4??" if its possible lemme have a quick reply…. i mean any Sim i can cut into the exact same size of the micro sim i phone will activate… i m in SriLanka so i need a help plzz
It’s perfect, it makes my day bright and different
alternative
It's just like Apple to try and make things complicated. Fist the Activation, then not having features in iOS4 for iPhone 3G, and now a Micro-SIM. They're trying to be like SONY and make something like Blu-Ray when really a Micro-SIM in just cr*p and a waste of my time.
My daughter Nurshaza cut it with a pen knife and trim it with a fine sand paper waalaaa its work great on my new iphone 4. Now busy playing High Noon and kill ALIBOMBA the bibir ha ha ha.
What if i have a contract and a phone already by the iphone 4 with the carrier i am already with? Will they give me the micro sim card? will i have to pay for it? and will i have to pay the activation fee again??
I am planning to buy a new Iphone 4g in Canada from fido…but my son will take it to Pakistan in 4 -5 month….my question is that when I ll buy my iphone and get the new micro sim…after my son takes it to pakistan will fido give me a normal sim to use on my other phone?? plzz reply
Look out for a mini sim holder, that can take a micro sim. Try Ebay
I went to my current service provider (Rogers) and asked them for a micro sim card today. They sold it to me for $10.50. All i need to do is activate it over the phone which yes…its a huge pain but whatever, i want this phone so who cares. Its simple and not that expensive.
I am getting my iphone 4 from US. I will unlock it here and cut my existing sim to micro sim format. I want to explain the process of changing existing sim card to micro sim card in my blog. Hope it will take 15 days.
I am looking to buy a brand new iphone 4 from my friend for 100$. I have an unlocked 2g iphone right now. I was thinking about asking for one at the at&t store but would they check my number if im already on the iphone plan? I was also considering to cut down my 30 day trial sim i got from buying a go phone just to be able to jailbreak and unlock. Does anyone have any other ideas or thoughts, would this work?
Hello,
I just bought an unlocked iphone 4 thinking I would just phone up Orange and request a micro sim but they want to charge me an extra £10 a month just because it's an iphone and I already have a 500MB data package.
If I cut my sim card down and use it can the network tell what phone I am on and charge me anyway or can I just carry on with the tarif I'm on unnoticed?
Hope someone can help.
Regards
Hi Jimmy, i am thinking of doing the same,did it work?
HI,
I am planing to buy an factory unlocked iphone 4 only for Canada. Also, I am visiting US for a while and I will return to India in a month.
Will this iphone work on India telecom network.
Regards,
Factory unlocked iPhones should work just fine provided that they can read the SIM card fine. I have a Canadian factory unlocked iPhone 4 and it has no trouble with my AT&T Sim card that I cut down myself.
hi ,
Could you please provide me the contact for the Canadian factory unlocked iPhone 4 ?
Thanks,
Vinay

I have an iPhone 4 I bought unlocked in Canada. I went to California and bought an At&T micro. Sim. It shows that I have 3G reception, my phone works ok but it says I am not subscribed for a data plan. When I go to AT&T it shows that I have purchased a data plan.
Any ideas?

I have an iPhone 4 that I purchased in the US. I am moving to Italy in September and want to take it with me to use there. Easy enough or too complicated to bother? There should be a dealer in Milan who knows how to modify it, right? Any ideas on the cost?
