That little thingy to the left of the SIM and MicroSD slot; is that an external gsm antenna?
I guess for attaching to a signal booster of some sort..?
Sorry for the potentially dumb question.
No it was also on the SGS1 .

Seen these on a lot of phones going back 10 years or more, so you are most likely correct.
I was thinking possible satellite extension antenna, but the old phones didn't have this.

Hey,
So I have some problems with service range, after I checked my SIM with other cellphones and checked my cellphone with other Sim-Cards I found that I have some problem with my antenna, the question is what should I replace?
the Antenna or the antenna connector cable?
What leads you to that conclusion? Merely checking your sim card in other phones and other sim cards in your phone has no/little connection with your antenna or antenna cable! There are easily a dozen or more hardware problems that could cause service range problems, not to speak of software problems! One of the first things I would check is what modem you have. Different modems act differently depending on your location. As a last resort, instead of mucking with your hardware, contact T-mobile customer service. You may be able to send it in for repair/replacement.
Hey, I bought the cellphone in the states but I'm using it in Europe so I cannot send it to T-mobile...
Anyway - I tried to switch modem version, back to stock, change roms but all are the same "****y" range..
I'm pretty sure that this is an hardware problem (while I'm holding the phone in the bottom the range is gettin really low...) the question is what I should replace
any suggests?
I have T-Mobile and I want to buy the International Samsung Galaxy S II. I understand that the International version does not support T-Mobile's 3g frequency band, and I would be limited to 2g speeds. However, I was wondering if it would be possible to buy an external antenna to be able to use 3g speeds. Or even better, is it possible to replace the internal antenna?
No and No.
DO NOT DO THIS UNLESS YOU WANT TO KILL YOUR GS2.
Sorry for the bold, but despite there being no rhyme or reason for it, I came across a thread which illustrated this fact from multiple people who tried external antennas, and here's what happened. The antenna worked, they thought all was good, then they disconnected the antenna, no signal. EVER again. I guess what happens is when you plug in an external antenna it pushes some contacts apart which breaks contact with the internal antenna permanently (supposedly a few that were very handy with a VERY tiny needle were able to fix it). Don't ask me why Samsung would design it this way while leaving the plugs exposed but that's what I read. Just wanted to make sure you didn't find out the hard way
In other words, the jack is there, and you can find adapters for those jack(s), but you really don't want to, unless you want to ONLY use external antennas for the rest of time (not most people).
EDIT: Whoops, forgot to add the most important part. Antenna has NOTHING to do with the fact that the radio doesn't support t-mo's frequencies. It's like having an antenna designed for HDTVs, and hoping to get hdtv on your standard def tv. Antennas don't "translate", they're all just fancy coathangers.

"antenna has nothing to do with GSM OR CDMA bands." its the radio chip that does the work.
Please use the Q&A Forum for questions Thanks

Understood, thanks for your help guys. Is there a way to mark this as [Solved] or something?

Yes. Edit your first post to an eye-popping "SOLVED"
interesting discovery for myself a little bit ago and i cannot find anything on google relating to the rezound being capable of using either sim
i dont have pics, but i've only seen rezounds with the larger white sim
and now i'm finding out that its capable of using the micro sim (thanks swilbert80 for bringin a few more hours of my life into sim research, inadvertently of course) lol
first, i wonder if there is a performance gain using a micro sim?
seems like it is generation 2 sorta, for all i know they work just the same - but i find it very interesting that its never been discussed (or at least i cant find)
ive swapped my sim out once as advised by technical support to resolve poor 4g reception - nothing was said to or mentioned of trying a micro sim,
anyways, any and all insight appreciated, curious to know what others have as a percentage...
thank you for lookin

The only difference between a regular SIM and a MicroSIM card is the physical size different, the actual circuit and contact part of the SIM and MicroSIM card is identical.
As for resolve poor 4G reception due to SIM card? Man tech support say the darnest things. It has NOTHING to do with 4G reception. It's nothing but an excuse to keep you in the loop while they won't admit it could be either the phone or their network's problem.
Going back to the topic. I have the first generation SIM card from Verzion as it came with my good old Thunderbolt.
I've been wondering though, when the next gen iPhone which supports LTE is released, if a simple SIM swap would complete the process of activation like between 4G devices now is going to be applicable or not...

Actually sims can go bad, it's a computer chip and they can interfere with a lot of things on the phone, it's main purpose is for authenticating and utilizing the radio in the phone, so bad sim card = tons of connection issues.
I experienced it with an old AT&T sim which I used to switch between phones a lot. though micro-sim vs regualar sim is irrelevent, they are the same thing just cut different.
Just getting a new sim, either kind should fix the issue if you have a bad sim.
A simple sim swap will do the basic activation of the lte iphone when it comes out just like swapping androids.
The only exception is that iphones interface with voicemail and sometimes data differently (at least as of IOS 3.0, it may have changed.) so a call in to verizon may be required to switch the plan your on. I've dealt with this when switching between iphone, blackberry and android on my AT&T sim. That really depends on how the carrier sets up the plans

I guess they don't make SIM cards like they used to be.
My mom's SIM card, which she was given back in 1995... yes, 1995, is still kicking and works just fine even after it's being clipped for MicroSIM across 20+ phones she had in the years.
bummer, i was hoping for someone to say that the micro was gonna be the bees knees... ( yall coulda lied, i believe in placebo's)
lmao
owell, guess i'll suffer with my oversized one lol
its easy to remove and replace i guess

Lol, personally the regular Sim card are about the right size for me the micro ones I fumble around with and drop it a lot, lol.
Sent from my ADR6425LVW using XDA
I almost fell out of my chair when I read about the sim card doing bad reception. Even if one is going bad. Most chances are its is either going to work or it isn't. Not kinda work. A fellow Rezound owning friend and I was talking about this subject yesterday. I don't think cdma carriers have the whole sim card technology ironed out yet. I had ATT for many years and I never heard the stories of people needing to get sim cards swapped out because of something not working or because they changed phones like I have since I been with Verizon. Seems like just about every person who switches phones has to get a new sim card.
Does anyone think there's a chance this tablet has a modem in to that can be enabled by porting over parts of a dump from one of the cellular versions? Long shot but not use to wifi tablets even having the pins for sim card.
i don't think so, if it has been designed to be working without a sim, there's a reason for it. the only way would be to replace the entire motherboard with the t975/t976 version, so you might as well buy the sim version.

Oh I get it, this is just the first wifi only tablet I've had, that HAS the pins for a sim card, I'm not taking it apart, but since it has a 865+ it would be insanely easy if there's a teardown to tell if it has the hardware, since the modem is now a separate chip with this snapdragon, granted you would need to decan the motherboard to do so,
Samsung used the same SIM/SD Card combo tray for all S7/S7 + models.
You'll notice the filler piece on the opposite side of the SD Card side is shaped like a Nano SIM..
The filler is removable and is marked under the black sticker as a SIM slot.
That said, I doubt Samsung is going to include the radio package in a disabled state on a Wi-Fi only model.
The one teardown video I could find of a Wi-Fi only model S7 did not show any cellular radio antennas. I can only see Wi-Fi leads. Definitely do not see any 5G antennas.
I just bought tab s7+ wifi (T970). While i was trying to insert microsd card into the tray i realized it also has space to insert sim card in it. First i thought it might just be it so that Samsung doesn't have to make another tray for wifi models. Then i saw sim connectors inside the slot. I tried searching it online,what other people had to say. Most of the people said that there is no modem for it,some said it might be a software limitation. As far as i know the snapdragon 865+ has an inbuilt 4g modem.If there is no modem in it, then why add connectors for it on the first place.
It would be great if anyone with a rooted device can try flashing firmware from carrier,or just check if it was possible to get sim working.
My T870 has the same thing. Instead of producing two different trays, Samsung put a blank where the SIM would go on the WiFi only models (T870 and T970). Just because you can pull that blank out and insert a SIM card doesn't mean it will work in your T970.
You can try of course, but it won't work. Nor will it likely hurt anything.
Yes, the Snapdragon 865+ has a built in 4G modem, but unless it is enabled in the firmware, it won't work. By firmware, I am not talking ROM/OS level. I am talking chip level firmware.
And even then I'd assume there are no 4g antennas in the WiFi model!
This has been discussed before.
The SIM tray is simply plugged with a blank on WiFi only units.
The SIM/SD Card slot is there (most likely to keep parts and manufacturing costs down), but it lacks a 4G modem and does not have any cell antennas.
