When attempting to call outbound, I often receive very annoying busy signal, and then it hangs up. This will happen up to 20 times in a row,regardless of my location. This is an upgrade from my old phone which never had this problem with the same SIM. Called Att with out much help. Any ideas?
How old was the old phone for starters?? Also if the Sim is the same from an Older phone sim technology has changed a little bit over the years so that might also be an issue there. I would go to an AT&T Store and have that checked out. Suprised AT&T didn't think of that although honestly they are not taught to trouble shoot very well I should know used to work apple iPhone tech support and AT&T has Horrible Tech Support. LoL I remember one time I called them and than got transferred back to someone in my own call center.

Yea, the Phones is brand new, still have 26 days to return it. But I like it. The SIM is about 2years old. I'm gonna go to the AT&T store today and see what they can do. I'll post after to help anyone with the same problem.

I'm sure this question has been asked before, and I'm expecting the "use search"flame but, I'm on my hd2 over edge at god awful speeds...anyways...
I've had it with this phone, it's terrible. I've had it since launch day, and I'd hoped I would get used to it by now..not the case. before I got this phone I was considering the n1, until I found out it was only upgradeable for individuals. My question is, if I buy an n1 outright, will I be able to get my sim card and put it in and it work?I have a family plan with unlimited data. (T-mobile obviously)
Yes, you can just pop in your exist T-Mobile SIM card and it will work.
Rock on, thanks man.
To add... when I was signing up for my account (I bought the phone outright) I asked what plan options are available. They said I could even use a prepaid SIM in it, they didn't care. Obviously the prepaid would be cheaper depending on how much I use, but you have to keep an eye on it.
From the 3 different TMo reps I talked to, they said your plan is tied to the SIM card, what phone you put that SIM card into, doesn't matter. That's what I was told, hope it's right and hope that helps.

100% correct. I bought the N1 with ATT 3G bands and just slammed my SIM card in it and away I went
Sweet, since I'm here and got more responses than I thought...from the general consensus, what are the biggest "faults"of the n1?
anything like buggy sms, outdated OS, freeze issues, lockups, <24 battery life it anything like that?
Also this if more a personal preference but, I've had tmobile for 3 years now, but I'm really starting to get irked at the lack of 3g and better technology, would it be worth it to break contract and switch to at&t? I just renewed for another 2 years with tmo so I think it's like 175 it something for early cancellation.

nothing so serious as any of those things, the common issues is 3g connectivity being spotty (but they have fixed this for the most part) and touch sensitivity bugs (nothing I've experienced). Tmobile is currently adding 3.5g all around america http://t-mobile-coverage.t-mobile.com/coverage# see the ling in middle of page to see cities with it and what is comming.

Poor Exchange support so if you want this thing to play nice with a work account good luck.
But other than that, there are no show stopper bugs/defects. For the most part the Nexus One with 2.1 is a solid consumer smartphone and there won't be any worry about outdated OS since Google will push out updates to the N1 first and if you're too impatient for them to push it to you, you can always find it here.
About the 3G issues, you may want to check this post which explains how T-Mobile shows their data speeds and check AT&T's coverage map for your area to see how they compare.
I would absolutely not go to AT&T from T-mobile. You're much better off on that side of the road, bro.

2nd.coverage may be good but service is terrible.dropped calls and privacy breeches as well
Ok, so this might be more of a rant than it is a question, but I am still curious as to see who else here has had to deal with the same thing I have.
Back in December, I finally managed to wiggle out of my AT&T contract so I could swap over to Verizon like I have wanted to for a long time. I really only had two reasons for wanting to do this and that was data caps and very poor service for my area(s). Before I made the switch, I actually borrowed two different cell phones from friends and tried them out around my residence just to see what my service would be like. Knowing that I live basically in isolation (one hour from the nearest large city) I needed to know that I would get decent reception.
Seeing that I was going to get perfect cell reception, I pulled the trigger and signed up with Verizon for four phones. Awesome. Up until three weeks ago, I had nothing but the best service you could ask for. Anytime at home you could make calls, use data and do whatever you wanted/needed to do. Sweet.
Then along comes Spring time and with it came its naughty sibling: thunderstorms. Now, I know all to well from working in telecom that wind, rain, and lightening can do some pretty awesome stuff to our telecom and digital communication services, so when a nice storm rolled through my area, I wasn't totally shocked to notice having no cell service that night when I got home from work. The next morning, the problem was still there. Again, not a shocker and no big deal in my eyes as stuff happens.
The storm in question happened on a Thursday, and by Saturday evening I was getting a little distraught by not having any service at the house. Mainly because I'm also a small business owner and I am always on call with work. As you can imagine, having a reliable cell phone and coverage is very important to me. As most would do, I called Verizon and voiced my concerns and they issued a trouble ticket.
Two days later, they call me back stating that," the issue resolved itself and that I needed to check my service when I got home and call back should I have any other issues" Again, I work in telecom and this line isn't new to me. This excuse is usually used when a company acknowledges that there is an issue but can't seem to find the cause.
When I got home, there was still no service. Let's be clear, I'm not talking about poor service at this point, I'm talking about clearly, no service. Not even a hint of Verizon or U.S. Cellular signal for an entire three mile radius of where I live. Once again, I call Verizon and submit another trouble ticket... Three days later, Verizon calls me and states that they found one of the cell towers in my area that had a missing neighbor ID. Ok, I guess I can understand that causing some issues, so we'll see.
Still no joy. So I made yet my third call to Verizon and was told that they had done everything possible to resolve my issue and that my area is now considered to be a marginal coverage area, so I would have to deal with the issue or pay my ETF and use someone else.
As you can imagine, I complained until I got high enough on the food chain and got someone who is/was willing to look into the issue.
In the grand scheme, I've been getting excuse after excuse from Verizon and now I'm beginning to wonder if I should start looking into getting back with ATT because of this. I'm being told that they will hopefully have someone out to look at the tower within 7-10 business days (as of today)
Thoughts?
File with the FCC. If they HAD service where you live when you signed, and now they don't it CAN BE construed as breach of contract on their part. The FCC may help you with either getting a better response or get you out of your contract with Verizon with no ETF. Just know that it will take a couple of weeks to get resolved through them.

FCC, huh? I know I don't need help getting out of my contract. They blantly offered to let me out of contract on the second phone call. Either I was complaining heavily or they aren't concerned about retaining customers. I really want them to fix the problem and not just cut me loose. It's not that I can't afford to change carriers as I could sell all four of my Droids and have more than enough to go with ATT. I just don't want data caps and Tmobile and Sprint have no coverage in my area. I could hack Sprint enough so that it would work with the Verizon partnership that's in my area, but I really don't want to do that. Although, if Sprint came out here... I would be nice. lol

FYI: If you do go the FCC route (I really hope you don't have to though) you will be contacted by Verizon's executive office. Telecoms have no choice but to respond quickly (and most likely in a favorable way for/to you). GL.

Well, as an update, I'm still working with Verizon in an attempt to get this matter solved. I'm starting to wonder if they haven't decomissioned a tower in the area for one reason or another because using some software with work and just knowing the general layout of my area, I can't see a Verizon cell tower for about a seven mile radius which uh, isn't right or it wasn't at one point.
Right now they have me marking my calls when they either drop, have poor call quality or can't connect at all. All I have to do is when this happens, I just dial ***** so that on the record it tells them to go back and look at the call before it. Supposedly, they can go in and look at which tower the phone used, transceiver on the tower and the node on the transceiver.
I still haven't called the FCC as I'm trying to be patient as I can be. My next step is to start turning in trouble tickets from my company's account that has something like 320 different Verizon lines. That's cell phones alone. If you threw in netbooks and air cards, you'd be looking at over 500 devices.. Maybe that would get their attention. I dunno.
Sorry to whine, but I had to share how bad of an experience I have had with this phone on Sprint and was curious what advice you could all offer. Basically I bought the black 16gb version on google play. I was told by Google via telephone that day when I get the phone to just call in or bring it to sprint to activate it. Well after an hour on the phone they don't know what to do and tell me to wait until November 8th. This is silly as others have had it working.
after getting disconnected about 3 times with sprint trying to activate the phone, I later learn that I need a sim card, which is disclosed no where. I was never told about this and had to research it ON MY OWN to even learn about this. I hear that it's also difficult to get one and that you may get push back on it.
Then I learned my speaker was dead on arrival, so now I am waiting for a replacement phone of which they can't promise me free two day shipping which I paid for in the first place, only to receive a defective phone. What the hell? Oh and I had to call back because I never got my confirmation and make a whole new claim. Now my order is stuck as a pending status and who knows how long it will take to ship.
I have to ask, how in gods name can sprint say they support a phone but have no information or literature out there to support the phone? WHAT WERE THEY THINKING?!.
I worry I bought a 400 paper weight that I'll never get working.
So I don't get it, are you upset that your RMA is taking ages due to a defective speaker or because sprint couldn't activate it on time?
What if they had activated it, the speaker would have been defective anyway, right?

It always fascinates me that consumers in this country (and others I'm sure) have reached a point where they expect everything to be spoonfed to them and that they should have no responsibility in actually researching or learning about something they're about to spend $400 on. Do we as a society just have too much disposable income? I acknowledge that $400 isn't what it used to be but still, if you're concerned that you might be unhappy with your purchase, how much of the onus is on you for not knowing what it was you were buying in the first place?

It sounds to me like it's a combination of both and he is just really frustrated at this point. I understand completely as just have to talk with Sprint CS is infuriating enough.
Instead wasting time on the phone with incompetent CSR's, why don't you just bring the phone to your local sprint store grab a sim and be done with it?
ummm you didnt know that you needed a sim for the phone?? really??
How could you not know you needed a SIM card? These things don't magically connect to every network on the planet.
Every phone needs a SIM card to make calls, use 3G/4G, send texts etc. mate - you've been living in the dark ages or something?
Sprint and Verizon back in the day did not need the Sim card.

I never understand why some people don't just go into the store. Unless they are rural and they can't get there. Thebsims are in the store and can be activated on the spot. Sucks about you r phone but do some research next time.

Right and wrong. Carriers that use CDMA for 3G such as Verizon and Sprint don't need SIM cards to activate devices on their CDMA network. If you want to use LTE on those networks however, a SIM card is required. This is because LTE is technically a GSM technology. Not that his post is any less incorrect, I'm just posting to inform.
LTE - SIM
3G & WIMAX - No SIM
My SIM is being delivered tomorrow along with my 32GB Nexus 5.
Looking forward to the headaches getting it activated.
You shouldn't be upset the RMA. Trust me, it will come very quickly and you won't pay for shipping on it. I did it with the Nexus 4 on Wednesday, it was in my hand on Friday.

You "MUST" research everything you buy or this is what will happen. I ordered my 32g yester after only researching to find out that it will work on Sprint. It took a few hours of search, but in that time I ordered the Simm that I researched that it needed from Sprint via international chat for free. It was back ordered and my phone won't ship until Nov 22 anyway so hopefully it will be ready by then. I also ordered this case which should be here before the phone.

You can't blame Sprint for not knowing about a device that won't be available until the 8th for activation early now can you. Those that got it early and activated it early should feel that it is a privilege for this to happen. In your case you could have gotten it activated had you thought outside the box. There are tons of Threads about how to activate these all over the internet!

I can blame them when very few stores actually have Sim cards in stock. If you go to any ATT and Tmobile store I guarantee they have Sim's in stock. It's not like this is the only phone Sprint accepts on there network that has a sim.
Need to know if the problem is with the phone or provider.
My husband went back to Sprint due to lack of coverage & these service issues.
We still have the same problems. Almost every time he calls me, regardless of where he is, the call does not go through. It rings a few times and then just drops or goes to voicemail, never ringing on my end or showing a missed call. On the 2nd or 3rd try it goes through and I get his call. Now this also happens when I call him. There are also many times when we connect but one of us cannot hear the other.
I am mainly at home, while he travels the U.S. as a truck driver. Tmobile did provide me with some type of signal booster for the house, but it doesn't seem to have really done anything to help with these issues.
We now are paying for 2 plans and for 3 Note 4 phones through Tmobile. This is hurting us both emotionally & financially. My husband hates to call me and our 10 calls a day has become much less & when we talk he is already upset having had to call me 2 or 3 times to get through.
At this point he wants me to join him on Sprint, but we are already paying more than when we left Sprint & we are by no means rich.... The worse thing is We are paying for 3 Note 4 phones that cannot be used with Sprint. I had to downgrade him to a Note 3. Worse I sold our Sprint Note phones when we moved to Tmobile. This is just such a nightmare.
I have to find a way to fix the issue or I will have to go buy another phone & go to Sprint & continue paying for Tmobile until all 3 phones are paid for
I had similar problems, you can try to turn off VoLTE, voice over LTE. What number has your signal transmit booster? How many bars has the receiver booster? How many bars you have without the booster?
Edit: Welcome to XDA!
wow that sucks... ive experienced similar issues. im pretty sure its a service problem. i cant imagine 3 different phones have the same problem but then again im in that exact situation. ( all 3 note 4s have the same issue). try putting you sim in an old phone and see if it clears up. try to isolate the problem to either the phone or service.

Well first it might be ur phone. If ur signal is not strong at home tell Tmobile and u will get a booster for your house. Also have them refresh u on network. On his end if he a truck driver T-Mobile nor any carrier covers all of the USA. You gonna have dead spots while driving thru ghost towns. If he is in major city then he should be good. No phone works every place. I have had them all and while traveling Verizon was the best but my ass bleed paying 400-700 a month for my phones as data was a killer. Now I don't travel as much and Tmobile has been great.

Thanks for replys... it was a defective phone!
I cannot believe after over 6 months with the same problem no one at T Mobile ever suggested it was the phone. in the very beginning they did replace the SIM cards our phones but it did not fix the problem. after giving it a lot of thought I realize that my phone was the common denominator in the problem. I put my sim card in our backup note 4 phone that my husband is obviously no longer using since he went to sprint. All weekend my service was fine. my husband was able to call me and get through and I was able to call him and get through every time. T Mobile is going to send me a replacement. Very happy that it wasn't the service and that I'm not going to have to switch to sprint which would have been a severe financial hardship for us. thank you to those who replied trying to help me with this issue. Much appreciated

well the 1 st part of ure message is just inexperience. just use and learn as you go. i mean no one can teach you what you will understand on your own just by trial and error. of course you can always search and read the internets..
the 2nd par is also inexperience. just check what the carrier's mobile technology is using (is it GSM or CDMA? very easy to search for) and AFTER you should have bought a device compatible. now in order to identify for sure why the device dosent work on X carrier. you need to tell us what acctualy that X carrier is. also what is your defenition of not working? do you get a particular message when you insert the sim of that X carrier? or is there just no signal?
anyways once we know what carrier it is and the particulars of the issue, you might end up simply switching to an other carrier that supports GSM( because i suspect that is the issue at hand, your carrier might be CDMA but your device requires a GSM carrier).
I'm going to assume you're from the US. I checked the Sprint LTE bands which are, 25, 26 and 41. The SM-N960F (International phone) supports 25 and 26 link and the SM-N960U (US phone) supports 25, 26 and 41 link. So the fact you're missing band 41 is probably going to be your issue.
