My 5S does not recognize the SIM card although the card is recognized by another phone

I bought a new SIM card in Brazil for my 5S after it was blocked because I had lost it for about six weeks.
The phone did not recognize the SIM card. Thinking it was a hardware problem i took it to an Apple store in the US where the assistant showed that her sim card was recognized by my phone. However my SIM card continued not to work in Brazil. A colleague's SIM will not work either in my phone but my SIM card will work in her phone. What could be the problem?

What is the EXACT message you get?

Hi i just ended my service with my service provider and was wondering if i have to do anything to use my iphone 3gs with another carrier. do i need to get it unblocked to be able to use another sim card

I just ended service with my at&t and was wondering if i have to do anything like have my phone unblocked to use another sim card or use another provider

I have a 3GS, out of contract with AT&T. I emailed for the unlock, and got an email saying:
"Request number: (xxxxxx)

Now the deal here is, iOS 6 is out now, so in order to complete the instructions and restore it with iTunes, you have to update to iOS 6. I decided to keep 5.1.1, so I did NOT restore the phone. I checked a couple IMEI checker sites, and they all said my IMEI was unlocked, so rather than use iTunes, I just replaced the AT&T SIM with an O2-UK SIM card I had when using my Android phone in England. I was pleased to see T-Mobile show up as my carrier when I turned the iPhone on, and in Settings, it shows O2 as the carrier instead of AT&T, due to the O2 SIM being installed. Then a moment later, I got texts saying what my remaining British £ balance is, since I had leftover money on the SIM from my last trip, and another text said "Welcome to America, have a nice trip!"
The phone isn't jailbroken or anything like that. It's still on 5.1.1 with the proper, working Google mapping. Never restored via iTunes. Never updated to iOS 6. Any SIM card works. No tricks or hacks. You don't have to restore the phone to complete the unlock.

Hello i try to use another SIM card with my iphone 4s now it said i need to unlock the phone with my Sim carrier

Hello i try to use another SIM card with my iphone 4s now it said i need to unlock the phone with my Sim carrier ... here is what it says below
The SIM card inserted in this iPhone does not appear to be supported.
The SIM card that you currently have installed in this iPhone is from a carrier that is not supported under the activation policy that is currently assigned by the activation server. This is not a hardware issue with the iPhone. Please insert another SIM card from a supported carrier or request that this iPhone be unlocked by your carrier. Please contact Apple for more information.

So.. You need to contact the carrier for the iPhone's original sim card, and request they unlock it. The carrier is the only one that can unlock the sim of the iPhone.

HT4623 after updating to iOS 6.0.1 my iphone 3s won't recognize my SIM card. i updated my phone through iTunes, what happened to my phone?

after updating to iOS 6.0.1 my iphone 3s won't recognize my SIM card. i updated my phone through iTunes, what happened to my phone?

If it now says "invalid" or "unsupported" SIM, your iPhone was almost certainly hacked to unlock it from the original cell carrier and updating has now removed that hack and the iPhone has relocked back to that original carrier. You will have to contact that carrier and ask if it would be possible to get your iPhone officially unlocked.

Sorry... but... ONLY the US Carrier it is Locked to can unlock it.
You need to Contact them.
Note: No one here will know who that Carrier is.

My I phone 3GS keeps saying no sim. How can I get it to recognize the SIM card?

TRy removing the sim card wipe it clean then insert it again. Your sim card tray might be dusty. Another option is turning your airplane mode on and off.
btw, is your network signal strong in the area where you are currently? Ask ATT if there is any area outage

No matter what i do, my iphone will not recognize any sim card that is put into the phone, and i have tried 3 different networks

Most likely the phone is locked to a carrier that you haven't tried yet.

If I unlock my phone can I pit my current carrier back ito it and go on as usual, saving the phone for use on a holiday and get another sim card and carrier

If I unlock my phone can I put the SIM card of my current carrier back in and wait until I am on a holiday to buy a New SIM card and a plan with a new carrier.

Yes, you can continue to use the same SIM and the same carrier even if the carrier unlocks your phone.

My iPhone5 prompts while setting up "This iPhone is not currently setup to work with carrier you are attempting to use.Please insert another SIM card from a supported carrier" or "Request that this iPhone be unlocked" How can I unlock my new iPhone5 ?

My iPhone5 prompts while setting up "This iPhone is not currently setup to work with carrier you are attempting to use.Please insert another SIM card from a supported carrier" or "Request that this iPhone be unlocked" How can I unlock my new iPhone5 to function properly?

That means that the phone is locked to a carrier other than the one you are trying to use.
ONLY the carrier it is locked to can authorize unlocking it.
Where exactly did you get this "new" iPhone 5?

Can i activate an iphone that is from Australia with another sim card?

If officially unlocked, yes...you can use any valid sim card. If carrier locked, no...requires a valid sim card from the carrier the phone is locked to.

As Kilted Tom said, make sure that you speak with your previous provider. ATT will direct you to a website and have you enter in some information which will determine if you qualify for the unlocking status. After you complete that, you will need to restore your phone as new through iTunes. Make sure that you have a backup to iCloud in order to retrieve your content and data after you restore your device.

HT4972 Why won't my iPhone 4 recognize my sim card after update?

Why won't my iPhone 4 recognize my sim card after update?
I updated my iPhone 4 over wifi and it went through the process fine, until it switched back on and now refusese to recognize my sim card!
Any ideas?

Usually this means the phone was previously jailbroken or hacked to unlock it from the carrier it was locked to, and the update re-locked it to that carrier.

I phone 4 dosent recognize another sim card.
