Maybe it's locked to a certain carrier.

Try cleaning the contacts on her sim card and then jiggling the sim card around once inside the S4. It might take a few attempts and a few reboots but should work.

[Q] How to check if phone is GSM unlocked

Hey guys bought my HD2 off craigslist and he claimed it to be GSM unlocked. This means i can use it overseas on those GSM carriers right? or on ATT here in the states? If so how can i tell it is truly unlocked? Thanks again great xda-developer members!

There is no such thing as a CDMA SIM card, aside from Nextel SIM cards that use the iDEN network. Try another SIM.

Yeah there isn't that's why I questioned the fact of the sim card being from a cdma phone. But you were eight apparently you can put the card in too far lol. It found the card and just said mobile network unavailable. No passwords or anything. So I'm guessing it is unlocked?

You have to have the correct size SIM card (the N4 uses micro SIM). If you don't have the correct size, then you can just go to an AT&T store and ask them to swap you out with the size you need. It should be free.

Well I can scan for networks but wont let me join any, even the one that the sim is (Cell C)
Did you try inserting the sim when the phone is off ? When I inserted the sim, the phone was on and it would not recognize the sim even after reboot.

How do you fix your issue?
Thanks for the help?
Did you use a sim cutter or did you use scissors ?
The sim needs to be completely flush on the tray.
Remove the sim and turn off the phone. Insert it, and power it on...

I dont think dual sims are normally sold in the US. I purchased my from hongkong. Although i live in the UK i do like to use dual sims. However samsung s7 has one big problem. You can either use 2 sims or 1 sim and 1 sd card combination.

Yes I know dual sims is not big in US. This unit will be sent to my family in India hence the dual sim question. There is a hack to use 2 Sims plus microSD card but that's for later. Right now I want to know if there is a way to use two sims on my phone's model.
Thanks!

One cannot use two sims atleast on the atnt model.

2nd Sim Card Slot

Are there any US carriers whose Sim card will fit in 2nd Sim card slot? AT&T and T-Mobile don't fit.
Why don't they fit? Both sim slots have the same network bands.
The US variants (included the unlocked models) are NOT dual sim devices.

Neither has a card the same size as the slot. Either too big or too small.
I have dual SIM. Att sim fits in both slots. Perhaps you have the wrong type of sim.

Been to 3 different AT&T stores no luck. Guess I will just put an SD card in the 2nd slot.

I would doubt the tray is because on the dual sim tray the same size card fits in both slots
So either you have the wrong tray.. Or you have a single sim phone
Does your phone show 2 imei numbers?

That's the clue right there.
On the box you will see two IMEIs.
Mine has DUOS on the box as well.
The tray for DUOS can accept dual sim cards or a single sim and microSD card.
With 1TB storage the need for the microSD is moot except perhaps if the need to transfer a lot of data.
For most transfers, wifi5 and airdroid suffice.

My sim tray is exactly like this
https://www.google.co.th/search?q=s...biw=412&bih=771&dpr=2.63#imgrc=wAlKBc0SGWlfdM
There should be no problem at all fitting both nano sims.

Can't really tell if you are being sarcastic or genuinely trying to be helpful. But yes it is a dual SIM card model, it has 2 imei #, under setting it shows the empty 2nd Sim card. No card fits in it. I'd accept it was my not knowing how to put a Sim card in a phone, even though my S8+ was also a dual sim model, if I hadn't been to both AT&T and T-Mobile stores and no one could make it work. Really glad you got yours to, but it doesn't fit in my device.

Calm down man. People here are trying to help you. Since almost no one here has ever had problem inserting sim card, and you don't tell us much about the detail, we then assume you have single sim variant, wrong sim tray, etc.
It would be a lot easier if you just take a picture of your sim card tray and post in here so we all can understand what really happen.
If you cannot post picture or whatever other reasons, just cut the sim card to make it fit. I used to cut many normal sims to micro sims and micro sims to nano sims in the past (nowadays, all operators in my country make 3 in 1 sim cards that I can pop out whatever size I wanted).
However, I am absolutelyx3 certain that nano sim fits S10 second sim slot.

The sim type for both is the same. So if your card does not fit in slot 2 I can only assume the wrong sim carrier has been supplied
I would either goto a Samsung experience store or talk to the supplier of the phone and advise them and try to get another sim carrier from them
But there is certainly no need for a different type of sim

Amazon. Pretty sure it's the right tray. The slot says microSD/Sim 2. Will take the advice of previous post and take it to a Samsung store. Not a huge deal it was just convenient to have 1 phone instead of 2 since I work on sales and have customers calling all the time
