Taking the Sprint Hero to Verizon

I know that Sprint and Verizon both use CDMA for their phones, but does anyone know if I could take my Sprint Hero to Verizon's network and have working coverage?
My sister just bought a Verizon phone and she has full coverage, with 3G, but my Hero frequently says it is roaming.

you can try... probably not gunna be easy to get them to enter that MEID into their system.

sprint doesnt charge extra for roaming UNLESS like, 60% of your calls are roaming, or something like that. In that case, they will actually call you and say "You're roaming too much, you should go to another cell phone provider" (unless the reps in my store are lying to people, lol... I just started working for sprint a couple weeks ago. Lots of people ask about roaming here)

No, Sprint doesn't charge for roaming, but if 60% of your minutes are roaming for 3+ months, they WILL call to discuss terminating your contract. As for Verizon taking on your hero, no, they 99% most likely will not. It's a VERY rare occasion they let a non verizon device on their network.

would be plenty easy to just sell your hero for a decent price and go to Verizon and get the Droid..

eww the droid?! id rather have an Eris. at least its HTC and u can still hang on XDA
HTC 4-life!!!

lol.. i'm not a big motorola fan, but i do like the high resolution screen..

I thought VZW used slightly different bands for EvDO than Sprint? Or maybe I'm just imagining that since AT&T uses different bands... hm.
Seriously, if you have that much of a coverage problem, I'd talk to Sprint about cancelling without an ETF. May have to talk to their retentions department... someone who works for Sprint could shed more light.
(Personally I'd switch to T-Mobile over VZW. Cheaper, and you have an international-standard GSM device ;P)

Highly unlikely Verizon will activate it since it is not in their ESN database even though they use the same bands. Sprint won't activate Verizon phones either.

yup, if the phone doesnt say sprint either on the phone or in the firmware they will not activate it on their network.

I used to activate non-vzw phones all the time. However, smartphones may not be handled the same.

pretty sure they'll take it...they started their "any app, any device" initiative in 2008

they won't take it. they specifically said they will only activate a phone if it's either unbranded or verizon branded. sprint branding is a no go.

Around here they're pretty much the same. Also, I imagine where I am is on the short list for HSPA+ from TMo.
Anyway, this is a tangent heh.

I don't think you can swap phones between the CDMA sprint network and the Verizon CDMA network. Don't they use different parts of the spectrum?

Not sure about the different parts of the spectrum, but you can definitely move a phone between Sprint and Verizon (from a technical point of view). But you'll have a hard time getting Sprint to activate a Verizon phone on their network. Not sure about a Sprint phone on a Verizon network, but they did make a big deal about their "any device" announcement in 2008, which said that they would allow you to use any CDMA phone.

1. while talk of changing esn is strickly verbotten(i believe?) if one were to find a htc hero that had somehow become corrupt and the meid had been changed to all 00000000000000000's it would be possible to fix with qxdm (the htc hero is essentially the sprint branded htc droid eris)
2. in order to activate phones on the vzw network generally one would *228 ota a cellphone, however in the ota process a vzw phones SPC is (almost)always 000000 while the hero from sprint has a SPC which is a randomly(?) generated number
3. a proper vzw PRL must be loaded to a phone in order to make calls on the vzw network
4. MDN/MIN SID must be properly programmed in order to make calls on the vzw network
5. at this point you will likely need the assistance of a nice vzw tech, as the phone will 611 to vzw, but will not make calls (afaik this is due to a-key authentication?)
if you get the right person at vzw, ask the right questions(why doesnt my vzw branded phone call?), and you have performed the other steps correctly you should have TALK and TXT within 5 min
note:
-you will still show you are roaming all the time (now ALL the time actually)
-afaik visual voicemail does not work
-if you want data expect to use WIFI or spend a good amount of time studying another VZW handsets various data settings and a good amount of time on VZW support(have not even tried this)
-neither i nor xda are responsible for what you do to your phones and as always anything you do is at your own risk!

Something wierd happended last night. I was trying to install that JIt Dalvik install by following the direction on the gumbo 1.5c. I also attempted to used the mapdroyd app Any event after a reboot I had and when it loaded no signal showed , a damaged SD card sign showed. When attempting to place a call it asked me to dial *228 nothing would result of it . Any event a reformat and install on the OS again fixed. All.Any one know of any reason why that would of happened. I was truly experimenting out of curiosity

I can, and its been done
I would like everyone to know I just spent the last 3 days figuring ALL of this out.
As my understanding is, you can change esn as long as you are and "authorized user" and your not stealing anything, therefore if I have two phones I paid for, and I have service with Verizon (which makes me and authorized user as per their TOS.)
then its not illegal. Anyways, for the sake of education it is possible.
I've swapped out my esn/meid. Transferred all my info via qxdm service programming. uploaded a verizon prl. rooted. and now im looking for a suitable Verizon based rom for the hero... I'm attempting to put a stock 2.1 eris rom on right now. (btw the phone texted and called just fine, I just want to have a complete verizon based rom for the finishing touches)

[Q] HD2 USA and AT&T

Hey I'm gonna buy a tmobile HD2 from a friend of mine and I want to know if it can be use with AT&T.
Also do I haave to get a data plan with this phone?

Yes it can be used with AT&T but you will not get 3G speeds due to the specific bands the phone has.
I have an international HD2 and am using it on AT&T without data plan because AT&T does not have the IMEI for my phone in their database and thus cannot automatically add the smartphone plan. I'm not sure if they have the T-Mobile HD2 IMEIs.

I too have an international HD2 and am runing it on AT&T. You can't use the T-Mobile US one - the bandwidth doesn't work on AT&T only an international version will work.

I was going to say the same thing they said

You can use an Australian HD2 with AT&T and get 3G speeds. Mine works just fine.
http://forum.xda-developers.com/showthread.php?t=633404

I am running an unlocked TmoUSA HD2 on AT&T and it works just fine. Other than the fact that I have no 3G with this on the AT&T network. I am very happy with the performance since I live in an area with no 3G coverage at all. I have to drive 15 miles to get into 3G coverage area.
Yeah Baaaby AT&T .... not!!
When in the hell is AT&T going to take expanding their 3G coverage areas seriously? I wonder what it feels like to be the AOL of the cellular world, all those customers and so little speed. This really sucks bigtime!

Do not put your AT&T sim card into a T-Mobile HD2. They will automatically "upgrade" your account to $30/month blackberry data. I had a $10/month unlimited that disappeared and I can't get it back now.

That is not true.
I've been using my HD2 on ATT for 2 months now and my plan has not changed at all.

I used a T-Mobile HD2 for 5 months on AT&T without any problems except for no 3G. I used the $10mo data plan and still am. I now use a Telstra HD2 and enjoy full 3G coverage on AT&T. Both HD2's are unlocked and yes, the AT&T sim works fine. Just don't walk in to their store and expect them not to hammer you with the $30 data plan.
There's a real nice fellow from Australia that sold me my 2 HD2's. Very honest and reasonable. If you want his eBay ID, anyone can PM me and I will forward it. Beware of other internet store sellers! Some are selling the same phones for $100+ more and some people have been either screwed out of their money or have gotten refurb/used phones. Honesty is in short supply these days so be careful.

I unlock it... Just call T-mobile and ask for the pin that was yesterday and today got it by email.
Now the phone is for my girlfriend and I she doesn't have any data plan and she doesn't want any....Can this be done? have the phone without any data plan on AT&T?

if they happen to add it on there (by doing a maintenance sweep daily), give them a call and demand that they put DATA OPT-OUT on that line.

Thanks ill call before putting the don card in....I thought that it was mandatory with the phone.

It IS mandatory, that applies to ANY smartphone. Whatever you do, DO NOT tell them you are using any smartphones. iPhones are all in their database since they were the exclusive dealers for them so it's impossible (as far as I know) to use an iPhone on AT&T without them nailing you for a $30 data plan since all the IMEI's are pre-loaded in AT&T's system. At least with the HD2's and other non-AT&T branded smartphones, they don't have the IMEI's and can't just hit you with the data plan.
It's in their contract, any smartphone use requires a data plan. Of course, they also hit you for a tethering fee as well for the privilege of using tethering (computer to smartphone connection) even though there's nothing special about it nor does it use the data service any differently. Just another way for AT&T to stick it to the consumer.

Nexus 4 and Straight Talk

I am planning on Straight Talk $45 unlimited 1mo plan.
https://www.straighttalk.com/secure/ServicePlans
From some internet research it looks like the best bet is to get the t-mobile compatible sim (since service prbs are with at&t compatible sim).
The problem is, t-mobile compatible sim is only full-sized - not for nexus 4 micro sim. Contracted their customer service, they confirmed no t-mobile compatible microsim.
Now I have two options:
1. get the at&t compatible microsim
2. get t-mobile full sized sim and then use sim cutter.
Which way to go?

I am not going to stay with t-mobile, I am talking about straighttalk t-mobile compatible sim.
http://www.straighttalk.com/ShopSims

Depends
It all depends on what you rather have. I personally will be going to Straight Talk too, but with the ATT sim.
ATT will offer better coverage (Also better wall penetration) in most parts of the USA, while T-mobile lacks in the coverage department they have great speeds in areas where they provide HSPA+. But as soon as you leave those areas if you travel a lot then you will be on EDGE a lot more.
I have seen people on the ATT Straight Talk getting 3mbs/1mbs to 7mbs/3mbs and those on T-mobile getting 7mbs/3mbs to above 10mbs/4mbs.
But like I said it really depends on what you want, I am leaving sprint so regardless of who I chose it would be a lot better.
If you go with T-mobile just cut the SIM.

I have straight talk and had tmobile b4. Where i live they both have strong signal get bout same speeds. I think tmobile will only help in bigger markets where they have the 42mbps towers not everywhere i tried to check the coverage where the 42 spots our cant really figure it out i live in a medium size market i dont get the 42 speeds here anyway so just something to think about.

You basically spelled it out right there. Which network do you want to use ATT or TMo. If ATT, pick option 1. If TMo, pick 2.
ATT has wider coverage, so you can go to rural areas and still get decent signal. TMo usually craps out when you leave the city.
TMo has better speeds in the city, since most cities' ATT networks are congested compared to TMo (more users). Add to that, since Straight Talk is an MVNO, it gets lower priority at cell towers compared to ATT postpaid and ATT prepaid customers. So you can stand beside someone with an ATT SIM and he has a signal, while your ST SIM gets nothing.
If you have the money to spare to buy 2 SIMs, try the ATT microSIMs first. If you're not satisfied, then get the TMo SI and cut it down. If you have the extra $60 to spare, get them both at the same time, buy a month's service for both, and so a side-by-side comparison.

also, do you use google voice for voicemail? I believe T-Mobile MVNO's don't allow call forwarding (which is what Google Voice does for voicemail). I could be wrong though, so make sure you do your search on that. http://forum.xda-developers.com/showthread.php?t=1890301
As soon as my contract (and my wife's) is up on AT&T in March, we are going to get the Straight Talk sim for AT&T...mainly because of the reasons other people have mentioned in this thread... plus, when I had the G Nexus, I got a T-Mobile prepaid sim to test it out and T-Mobile HSPA+ was slower here than AT&T.... but go with the coverage that works for you.

For some reason, I'm experiencing very slow data speeds with straight talk ( att Sim) with my nexus 4. Called them to reset my data settings but still no good.

I cut my straight talk/tmobile sim to work in my nexus 4. i refused to use att side of straight talk. so far everything is good no complaints :good:

What are your APN settings? Delete the first proxy, test again. I had a to reset data, then set the phone in airplane mode and back and retested.

I have T-Mobile, have always loved it. The reception in my office had always been on the line, but most of the time, with all my other phones, I've been able to get 3/4g most of the time.
With the n4, I NEVER get 3/4g in my office. Quite frustrating. Thinking about getting st att based on most replies here. Sucks I need to change based on the phone

I've been seriously considering the N4 with st8 talk but I've been a little hesitant because I want it to work everywhere I go i.e. work, home, parents house. if anyone has had the Verizon GNex could you respond with whether it works better or not? What would be the pro/con list? Everyone has opinions, I know, but please only from ppl who have the N4.

Folks, 6Mbps on AT&T's HSPA+ might be as good as you're going to get.

i9505G - Google Edition on AT&T -- LTE Working?

The title almost says it all.
Anybody out there with the Google edition running on AT&T have LTE speeds working?
Here in the Atlanta metro area, we are supposed to have LTE on AT&T, but the phone HSPA connects with only about 1Mb down and 0.1Mb up speed tests
How do we make sure the phone is ready to work on AT&T LTE? AT&T rep says "check settings" ..... ummmmmmm she probably has an iPhone.

Does your current data plan actually support LTE? Have you had an LTE phone previously?
It usually only comes down to 2 things.
1) APN settings. You can verify by going to Settings (she was right, sort of), More (under Wireless & Networks), then Mobile Networks and APNs. You should be using one named AT&T LTE with an APN name of just "phone".
2) Make sure your data plan specifically says 4G LTE for Smartphones. If it doesn't say LTE, you need to get AT&T to change it.

I've used this app in the past on AOSP roms and such, and it works great.

Did you just swap your sim from one phone to another?
I am curious because on another forum LTE is not working.
Your phone has the LTE icon in the status bar?
thanks

Had the same issue yesterday when I received the phone. Spent an hour at the att store swapping Sim cards, changing imei numbers and trying different apns. Finally did a factory reset and it worked. We felt stupid. Not sure if thats the case with yours but give it a try.
EDIT
Also came across another thread with the same issue and another person said they had to change the IMEI on the account to a demo model. We also did the same with mine just before the reset. Here's the quoted text.
Solved. I went to the ATT store copied down the IMEI of a demo LTE phone. Called support, gave them the IMEI and that allowed them to add an LTE plan.

Thanks everybody for the replies.
We tried all sorts of APN settings, but there seems to be a larger issue here causing problems on many or all Google Edition S4 phones on AT&T's network, and that is the IMEI numbers of these Google Edition phones register with AT&T as not supporting LTE and therefore AT&T's data plan doesn't have LTE enabled for those devices. Many owners of Google Edition phones are having this issue, and are solving it by getting the IMEI number in the system to register as a demo with slightly different numbers. Not all people with Google Edition phones are having this issue, because they are just using a SIM card from a previous AT&T phone that was already properly registered with LTE capabilities.
Seems like AT&T just isn't ready for these new Google Edition phones, and the customer service reps are not usually tech. savvy enough to figure this out.
I might add that I myself am on the T-Mobile network (this post was for my friend on AT&T), and I generally get LTE speeds in excess of 30Mb down and 20Mb up here at work where I get 3 out of 4 bars of signal. In the AT&T store nearby, I got 2/4 bars signal and my speed tests still beat the pants off the demo model AT&T had, which got 3/4 bars signal. I say this because I am paying only $100/month for unlimited everything on TWO 4GLTE phones with T-Mobile, while my wife was paying $120/month for the same with AT&T for only ONE phone. The way AT&T garners exclusive deals on phone model variants that we should all be able to purchase and jacks up the prices of service to double that of the competitors, it's time for people to jump ship and force them to become more competitive.

I'm in the same boat. My previous phone (Galaxy Nexus) was not LTE-capable, so after getting a new SIM card for my new i9505g, it's only connecting at HSPA speed. Online chat with AT&T rep wasn't very fruitful. They are saying that the phone is showing up as "unrecognized device" and is causing the issue, and there's nothing they can do about that.
I am about to take a trip to an actual store to see if they have more knowledgeable staff there. Any tips or tricks (or super-secret handshakes) I should know about while talking to them?

Yeah put your sim in an LTE capable att device, have them add the imei and you'll get the LTE plan. You should be good after that. Othwerwise, have them add a dummy imei or one from a display phone. Good luck at the store as this will probably blow their mind.:good:

Thanks for the tips!
It went surprisingly well. The rep knew exactly what the problem was (he figured it was a phone shipped from overseas) and went the dummy IMEI route. Within 10 minutes I had LTE.

Nice one. Glad you got someone that knew what's up!

finally got LTE on AT&T
Hey all! I have been scouring the internet trying to get my LTE to work for the past two days I have used every APN I could find as well as downloaded ther notification toggle app to try to enable LTE.
at one point I did have a LTE data plan but I guess not anymore...
anyways I went on the my att.com account and I somehow got to two different technical support chat windows. The first time I gave him my real IMEI# from my I9505G and he couldn't add the LTE plan because it was not recognized as an ATT phone. I then got a friends ATT phone she is no longer using that has/had LTE on it and after telling me it didn't work, then finally on the third time using 'technical support' she didn't ask for any IMEI number at all just told me it worked.
(I think it was the live chat I found on the support section of my AT&T or something) I am only mentioning this because of the three times I was on live chat I got one texct survey this morning (I was on live chat last night 3x)
I gave all 1's out of 10 (worst possible) but mentioned the chat person was friendly and that I was just unhappy with AT&T.
AT&T then called me this afternoon about the survey and asked if I wanted them to fix the issue..... Was this a real question?
I said yes and now I have LTE working great using the default phone APN that was on the phone from the factory.
Hope this helps some ATT users!!!

Switched to Straight Talk. I have 2 issues (slow speed and error message)

So as the Thread Title says, I have switched my Verizon Galaxy S5 over to Straight Talk, however i have 2 issues.
Issue #1 My HSPA+ data speeds are verrrrrry slow at times, currently averaging between 2.5MB/s and 4.1 MB/s Download speeds with between 0.8 and 0.95 upload speeds.
It has gotten as low as 0.12MB/s Down and .02 MB/s Up on HSPA+ I was wondering if this could possibly be an APN issue? Also it tends to switch between HSPA and HSPA+ alot but only seems to switch to HSPA when im not using data.
Issue #2 My phone shows an error This SIM card is from an unknown source. Is there any way to get rid of this without root (which we obviously don't have)??
Thank you very much for taking the time to read this.

Verizon phones are CDMA not GSM. Probably why you are limited to ultra slow speed for data, and also probably why you are getting an 'unknown sim' error being that the phone is verizon, and you put in a Straight Talk Sim.

Obviously you're unaware that the Galaxy S5 supports CDMA at LTE speeds AND GSM at HSPA+ speeds. The Verizon Galaxy S5 is a "world" phone and does not require any sort of SIM unlocking in order to be used on other carriers. (as i can show you with a simple screenshot). However i think my decrease in speeds is caused by a bad tower on the opposite side of town from where I actually live. While at home (with only 2 or 3 bars of service) i am able to get fairly decent speeds without issue. As far as the point of this thread goes i was wondering if anybody had any tips or tricks for better stability of the HSPA/HSPA+ network on the Verizon Galaxy S5 and to see if anybody was able to remove the SIM error without rooting. With rooting i know it can be achieved as i have already researched how to do so. I know why the SIM error is there, I'm not that oblivious. But thank you very much for your comment.

Your issue is very simple. You obviously didnt do your research before switching to straight talk. With straight talk you can have any carrier, you just have to have the right sim for that carrier. You probably got the t-mobile sim because thats the one they give if you dont ask. I have the at&t sim and it works perfect on my at&t phone. The only 2 sim cards you can get are at&t and t-mobile. You can use verizon and sprint with straight talk also. All you have to do is go to their website and it will tell you what to do. You have to look for the cdma section for activating a new phone if you want verizon. If you ported your number you can still keep it once you switch carrier options as long as you choose that at checkout. I just did all of this a couple of months ago and have done it several times in the past so I know what im talking about.

Not sure if you're aware that Straight Talk only supports T-Mobile. They used to support AT&T as well, but they switched to T-Mo. However existing customers that signed up when Straight Talk AT&T was around still get to use AT&T towers for now. There are some loopholes but 99.9% of people get T-Mobile when they sign up for Straight Talk as of today.
Straight Talk never used Verizon or Sprint.

Sounds like your issue is 100% APN.
Here are the APN settings for both Straight Talk and T-Mobile. Try the ST one first and then T-Mobile if that doesn't work. Don't know what to tell you after that, maybe try a new sim card.

I hate when people give out the wrong information. This is not the case and hasn't been the case for awhile. Do your research 1st. Go to straighttalk website and click on byop under shop. Now go to the very bottom where it says see all coverage and it shows the coverage maps of all 4 major providers. Now if you go with that same byop shop page and click on shop at the top, it will bring up a page where you can either buy a t-mobile or at&t sim, and on the right hand side you can also buy a cdma access code. This is not rocket science. Also, apns for every sim card for gsm and cdma access are different. I am not gonna list the apns because reply would be too long but its not hard to find. There are also numerous youtube videos covering this as well as multiple google results. I literally just bought an at&t sim when I upgraded to the gs5 because i had an t-mobile gs3 with the same straight talk service and didn't care for t-mobile. It is true that if you buy a straight talk phone from wal-mart then yes it will probably be a t-mobile phone but to say you can't bring your own phone and use whatever carrier is not an intelligent thing to say when you clearly can.

No need to get in a bunch. I wasn't aware that they started using AT&T and others again. Last year when I was network searching, STalk just stopped signing up new customers with the AT&T plans and their data limit was 2.5gb and not 3 like now. Sorry.

Nah I'm using the at&t sim. T mobile has garbage coverage out here. I bought the byop package from Wal-Mart that contains both SIM cards.
As for the people saying I should have done my research first, your input is irrelevant to me considering I'm not like every other person in this section of the forums. I know what I'm doing when it comes to this kind of things and of course I did my research ahead of time. So if you're going to come into my thread just to insult my intelligence, you can stop talking because chances are I probably know more about this subject than you do without having to have my face in a web browser.
As for the guy posting about apn, thank you very much for your input. I'll take a look to see if what you had linked is any didn't from what I currently have in my phone. However right now it won't make a difference because I'm being throttled down to .05 mb/s download and .08 mb/s upload.

I am not knocking on your intelligence here or anything, but you could have left that middle section out so you looked less like a turd for being rude to people just because they were rude to you. Two wrongs do not make a right.

Helpful tips on switching VW SG5 to Straight Talk
I have been trying all night to switch my boyfriends Verizon SG5 to Straight Talk but I can't get it to accept the SIM card or get it activated. For those that have done this successfully can you please provide me with the steps you took?

I did the same with an s4 and s5, but were slow and had horrible battery life. I couldn't get either phone to activate on the cdma network, so i used a tmobile sim. t mobile has a horrible network her, so I am pretty sure my issue was signal strength.

tmobile is pretty terrible unless you're in a major city. AT&T is the way to go through straight talk. However i would recommend Cricket, much better pricing and less network issues.
