S621 not working under T-Mobile anymore

Hey Guys,
Long time peruser first time poster. Heres the deal, got a HTC-S621 (on 8/15/08) with the Kavana_080408 ROM. Worked for a good while (until 8/23/08) until I used it on talkshoe.com then it simply stopped working. I can not receive a signal or on the rare occasion I do get reception, the phone can not communicate (no text, or calling service... Not even basic network communications)
but:
When I take the SIM out and put it in my old phone, the old phone worked.
When I use my wife's sim card from an alternate carrier, the S621 works.
The S621 does NOT work with SIM cards from T-Mobile.
I flashed the ROM at least 5 times (different ROMs) since the problem occurred, and the S621 still can not pick up the carrier signal.
so I'm deducing:
The radio is fine since alternate carrier sims work.
the sim is fine since it (and the recent prepaid sim i purchased) work in my previous phone.
there must be a registry entry or app that should resolve this issue.
Thanks in advanced for your helpful replies.

Reflash to 6.0 and see if the problem persists....if yes, return the phone with 6.0 on it and get a new one.

After the problem occurred, I installed:
The official Rogers WM6 rom
The official HTC Brightpoint rom
The official T-Mobile Dash rom
and the originally installed 080408 Kavan rom
of which an alternate carrier sim worked. The question still remains, "why do the T-Mobile sims not work". I have more affinity for the phone then I have for T-Mobile. Switching would be cheaper then buying a new phone but I would rather try to solve this issue.
Does anyone know how to force radio acceptance from the phone to the tower?

Maybe just maybe your sim is damaged?

Oh.. Your going to love this part of the tale.
Like I mentioned before, swapping out my sim for my wife's sim makes the phone functional. So of course I can't just take her sim, so we decided to go to the T-mobile store after church this past Sunday.
SO. I walked in and store and DEMOED the whole tragedy in front of the store rep. And I purchase a new sim for 20 bucks.
Put it in... booted up.... BUBKISS!
Then the Rep. thought the new sim was faulty or something so he got another new sim.
Same results.
Got my wife's sim.... it worked.
So I went home deflated and then I thought hey... it could be a lock on my number and the IMEI number, so I went back to the store a purchased ANOTHER sim. A pre-paid sim. 7 bucks.
El' NUMERO CERO!
But my wife's sim stinking works! Uhg!
So... Recap...
3 Sim changes
T-mobile: -3 Other Carrier: 1

Ok... to be fair... as stated above, my T-Mobile sim worked for a week and some days before problems arose.

hmmm weird.
Here's an idea, give your Dash to your wife?

Oh we wise guy...Why I aughta...
A friend of mine thinks it might be the antenna specifically the GPRS but then I trying to figure out if thats the case, why does my wife's sim work? why would the antenna presumably not work at 850mhz and olny work at 1900mhz and why doesn't the phone tell the t-mobile tower that? All assumption though.

Installed Dash WM5 image and it didn't help. Does anyone know where the antenna is located?

its internal

i would jus tell t-mobile about it... and maybe u will get a free one.. jus go off on them til u get one he he he thats wat i did.. wen one of my buttons stopwrkin..

hmm.. so its not likely that it can be jarred loose or is segmented physically for the individual frequencies.
Guess I'll get a sim from my wife's carrier.

That might work if i bought the phone. It was a gift from my brother... likely from a pawn shop or off of ebay.

Which leads you back to my suggestion

I'm going to switch carriers (via a prepaid sim) for a month then merge with my wife's plan if it lasts the trial.

Not happy with Samsung's repair service

i sent it in to fix my sim tray because it was defective. it came back and its brand new now. and it still wont read my sim. they told me to send it back to get it fixed. will it get fixed??

LOL we wont know, can you ask t mobile for a replacement phone instead of asking Samsung?

If it's brand new, maybe you need a new sim or a new mainboard?

This. If the SIM failed in the new phone, I'd try a new SIM.

have you ever though, might actually be your SIM that is defective instead of the phone?
it's extremely unusual for a phone SIM card slot to be defective twice
have you tried your SIM card on another phone?

Ugggggggh.

how did you know it's a brand new one ?
I've been told that samsung won't replace phones ,IDK

Why have you still not replaced the Sim card when everyone is telling you that is probably what it is?
Sent from my SGH-T989 using xda premium

its not my sim card. i put it in my bro's s2 and it works. other sims dont work. they said its the sim prong reader thats messed up. i dont have the reciept so i cant do it through tmobile. i already sent it in to samsung. when it came back, the sim was a little loose in the tray. its probably that. cuz the sim trays not broken. it keeps reading searching.

you can put a little piece of paper on it to keep it in place
also make sure you did put the SD card facing out
the cut corner should be facing out, not inside

Where did you buy the phone from? Did the Sim ever work in the phone? If it has, and it's not a used phone, T-Mobile's system will automatically see the warranty in the system.
Otherwise, if you have the php bundle on your T-Mobile account, T-Mobile will replace it under warranty anyway...regardless what the system shows for warranty information.
Sent from my SGH-T989 using XDA App

nope the sim never worked. the sim prongs where messed up when i got it.

searching for how long?
first start always takes a long time to find the network..

more than hours. its sent back for another repair

Swapping Sim between HTC One & iPhone 5

So I will be getting the HTC One. I'm currently using an iPhone 5, and I want to be able to switch between the 2.
I know the iPhone 5 uses nano sim, and the HTC One uses micro sim, so I will have to buy an adapter.
However, will it even be possible to just switch sims, seeing as Verizon is CDMA?
Thanks!

I'm doing this same thing with my S4. You will have a SIM in the iPhone and a SIM in the HTC One.
You'll need to go onto the website and swap the active device on the line (takes like 5 mins, super easy).
Even if you could just drop the iPhone SIM into the HTC One (you can not), you'd still have to set the IMEI for the device to be the active device.
This is how they track data usage etc. Activation takes up to 15 minutes, but I noticed in my area in socal it took only 2 minutes.
There is no additional cost to swap or use a different device. Did this myself this morning, rep assured there is no charge but they do present a summary of what the line (your phone number) costs monthly. Not to be confused with the IMEI and SIM numbers (for which there is NO cost to swap, add, etc).

I've swapped my sim between at least 20 devices without ever needing to change anything on the verizon web page. The only time I have ever had to have any interaction with Verizon is when going from a nano to micro sim. However I've cut three micro sims to fit into iPhones without issue.

That's way too complicated. Just buy a $5 sim adapter off Amazon and voila. I switch between my s4 and iPhone on a weekly basis and have never had to call verizon or use the website.

With sim adapter I've been using the Same sim and switching between my galaxy s4, iPhone 5, bb Z10, and lumia 928.

Ok, so it looks like there are a couple different options, and now at least I know it's definitely possible to do easily.
Thanks for the replies everyone, you're awesome!

**EDIT** Ha! Snap, 600th post. Sorry, had to, I got excited for a second.

I went by a Verizon store today to purchase an HTC One. At the store, there was a sticker on the HTC One that said "NFC SIM required to activate". The sales person didn't know if my nano sim / adapter would work at all in the HTC One. We couldn't even test it, because he said I'd be charged a $35 restocking fee if it didn't work, and if I decided not to purchase... I decided not to take the risk.
Has anyone actually tried moving an iPhone 5 nano sim to an HTC One (using an adapter)?
Can an active nano sim (non-NFC sim) be used / moved a new HTC One, or is a NFC sim really required to activate??

I have not and I don't know the answer to your last question, however I've decided I'm just going to keep the nano sim in the iPhone and keep a sim in the htc one and when I want to switch I'll just go to VZW website and switch phones, like the first answer said. It's real simple so for me it's no big deal. I'd rather not put the wear and tear on the sim and sim tray.

I switch between my HTC One, SG3, and SG4 but they all have same size SIM.
I heard adapters can cause issues
gotta love how apple does everything different until it comes to software that was in Android light years before iOS
how do I tell if my SIM is NFC?
I am still using my SIM card I got when I bought Samsung s3

The iPhone Sim works in the One.

how do you figure???
iphone takes a nano sim card. much smaller
either need adapter, or ruin his sim and cut it to fit the iphone and then no way to get it to work on HTC One.
correct me please if I am wrong.

ohh, no need to apologize, I am sorry as well. I understand your post now.

Then why would Verizon put a giant sticker on the HTC One box, proclaiming an NFC sim was required? Placing my iPhone sim in the One (with adapter) will just work? Hopefully this is the case.

This will not work. As soon as you activate the One VZ will "burn" your i5 sim. Same thing going the other direction. VZ will not allow you to have two (2) working sim cards.

Verizon used to disable a SIM after its been used... i.e. SIM A in phone, switch to SIM B, SIM A is no longer usable. So your plan might now work.
Instead, you'll likely have to activate the Nano SIM for the iPhone 5, then use an adapter when moving your iPhone 5 SIM to another phone...
Two SIM adapter options are -> http://www.amazon.com/gp/product/B009B9YWB4/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1 or -> http://www.amazon.com/gp/product/B009ABEA7E/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1 (i've ordered each of those, so I know they work ).

i literally just reactivated my nano sim, stuck it in my iPhone to make sure it worked, and then put it into my One using an adapter. works fine

I guess you can call Verizon and have them send you a sim card.
.. but only one lol
got one coming. just in case ever need one
they send for free and doen't charge for the SIM if anyone every wants to save themselves a trip to the VZW store
I had them send NFC SIM, didn't realize i dont need it but oh well.
she actually sent me two because their systems were slow and she never asked my address and I said ur sending it to my appt right, and shes like.. no.
she was very nice, apologized for not asking, and instead said f it and said ill just send one to you and one to the original order cos their computers weer sucking lol

[Q] New HTC m8 Question

Hey guys so I just got a new M8 through ATT. I was wondering since they shipped the phone to me can I just activate the new sim card and put it in the phone no problems? Or do I need to Activate the phone as well. I purchased and had it shipped from ATT. Just wondering since I never had to activate my nexus 4 and don't remember for my LG G2.
Thanks for the help!

As long as the sim you have is compatible with the carrier you ordered from, and your sim is currently working, you won't have any problem just putting it into a new phone.
That being said, it needs to be the right size simcard. The One M8 using a NanoSim. If your current sim is not a nanosim you'll need to go into the store and have them transfer your account information onto a new sim (this is usually done for free).

Depending on how your provider works, booting up the M8 with the new sim should deactivate your old sim if they're tied to the same number. If that's not the case, you'll likely have to transfer your account to the new sim over the phone or in store.

Warning T-mobile is sending the wrong Sim size

So I got my phone today and noticed that T-mobile sent me micro sim instead of a nano sim. I went to the T-mobile store near my to get a replacement sim card. I don't know why but something told me not to deal with the rep I was in line waiting for, it seemed like everyone he dealt with ended up pissed. I didn't listen *first mistake* and stayed in line I got up to the guy and I told him what was going on. He just grabs the phone out of my hand and says maybe you're just sticking it in wrong. So he tries to jam a micro sim into a tray made for a nano sim and manages to get it in. I said what the hell are you doing I just told you it was the wrong sim size, then he was like well I guess you're right. When he tries to get the sim card out he can't, so he takes it to the back to "work on it" 20 minutes later he comes out with my phone in his hand, I'm thinking alright got my new sim and everything is good to go. Boy was I wrong, the first thing out of his mouth was "well we had a little problem" and shows me the sim slot. Well the good news is he managed to get the sim tray out, the bad news is the sim card was stuck inside and it looks like they damaged the pins trying to get it out. I was like you're kidding me right and asked to speak to a manger because I couldn't deal with him anymore. The manager offered to replace it so he goes into his system and then tells me he can't place the order because the phone hasn't released yet. He told me I have to come back Friday get one if they have it in stock. Now I have a 800 dollar paper weight mocking me

this may have been the time when I would have punch him in the face, just kidding but that's f**k up !!!

You have no idea how bad I wanted to. I spoke to T-mobile today and they seem to think that the phone uses a Micro Sim, even if I ignored the fact that the sim they sent doesn't even fit in the tray Samsung website and on their own webpage under the what's in the box says nano sim. I hope they get it figured out or they will have a lot of angry people calling them tomorrow.

I would of said "I just need a nano sim please" then come home and activate it at t-mobile.com/sim

Good news I went to another T-Mobile store and he was able to get the sim card out. The funny thing is that he said I was the 9th person that came in with this problem and the store only been open for 45 minutes. He said a batch of phones went out with micro sims instead of the multi sims *the ones with the 3 pull tabs to choose your size* One of the guys in line behind me said that one of the support guys on the phone told him he had to try to use the micro sim to confirm it's the wrong one before he could get a new one or he would be charged a fee.

Wow! Insanity. I would have... I don't even know. There would have been loud words.
I had a similar situation with a much less expensive item in a store recently where I just stood there and watched as the sales person proceeded to try to bash something together (I had pointed out it was bent and wouldn't fit right ) which of course cracked the thing I was about to buy.
I got a hefty discount to say the least.
If it had been something like a brand spanking new cell phone I hadn't even been able to use yet??
It would have been his head broken along with the sim tray.

Got 100 off my bill for my troubles, what's funny about the whole thing is that when I called phone support they wanted to charge me full price to send me a new phone. I asked the lady if she was smoking crack, keep in mind this is the same person that told me that the edge plus use a micro sim instead of nano sim. She had no clue what was going on I had to explain everything to her multiple times. I must say this is the first time I've ever had any issues with T-Mobile.

Wow 200 off the phone bill is quite massive. How did you persuade them to give you that compensation amount or did you demand it? I used to get 40 dollar credits here and there for 'outages' during the days of sidekick device aha

That's weird the Sim card I got was actually 3 Sim card sizes in one. It came assembled as a regular sized Sim but had punch outs to reduce the card to micro and nano sizes... I didn't use the new one considering I had been using the nano Sim from my M9 anyway.

I've noticed that in store as well when I needed a new one. That's actually a good move and saves money. However, TMO needs to explain the cards to the customer.
