[Q] Can I use Tmobile HSPA+ Network

I just noticed yesterday that T-mobile has a 4G network in my area and I was wondering if there was a way to force roam 4G on tmobiles network? So that I could pick up 4G.
If its possible how?
Oh and sprint needs to hurry up and put 4g everywhere

You said it yourself. T-Mobile is HSPA+, Sprint 4G is WiMax. So, no.

Naa dude. HSPA+ is not compatible with cdma(sprint). Matter of fact t-mobile is using 4G now because its "trendy" and everybody else is using it. Their network is closer to 3G in infrastructure. But thats up for debate.

That sucks like hell. There's 4G here I just can't have it. AHHHHHHH!!!
Well if its like 3G I guess I'm not missing much.

You are on the money. HSPA+ is no more than an upgrade to existing 3G technology. If I remember right, it only has a theoretical max of 54 Mbps down. It is not, nor will it ever be, 4G.
Granted, the current 802.16e standard of WiMax is not 4G either...just waiting for that 802.16m standard to be finalized =). Which once that is complete, infrastructure can be updated and we should be able to utilize it with a simple firmware update.

No its way faster than your normal 3G. Faster than WIMAX too. Its nothing to pull down 7 or 8 Mb.

I bet it's better on battery than wimax is on ours.

It uses the same radio for voice. The EVO has a separate 4G radio thats has to be activated and scan then connect. So 2 radios running at the same time would use more battery than 1 GSM radio running. Also CDMA has a tendency to use more battery when searching for signal in low signal areas.

Having installed T-mobiles 3g upgrade here in Chicago market back in 2008, I can say definitively that HSPA is just a radio cabinet addition to the existing cellular framework. Depending on the layout of the tower/site, "Flex radios" handle the data on 1, or sometimes more antennae, while the voice travels over GSM through remaining antennae. Very similar to ATT infrastructure, but tiny radios handling big bandwidth.
Having said all that, 4G is a silly buzzword that Sprint started, and T-mobile is now exploiting.
In a way, Sprint is just using extra radios on top of their existing 3G cellular, and just integrating the enhanced data speeds of Clearwire's network into their own.
T-mobile's speeds are indeed fast both HSPA and HSPA+, but to call them 4g may be overstating it, as it is just an upgrade to their existing technology, and not a new technology.
As another poster stated, nobody officially has 4g yet, not even Sprint, and until the 802.16 commission finalizes and LTE is launched we still won't.
To re-emphasize to the OP, not a chance, and don't believe the hype.

I can see sprint(or clear) and T-mobile going to bed for some real 4G'ness.

Yeah, I heard a rumor that Sprint may eventually adopt LTE.... It makes sense.
Wimax will make a great backhaul, and could stay in place, not to mention supporting cities and rural areas. But LTE will be the big daddy, and similar to WiMax, works on it's own and should be seamlessly integrated on top of cellular.
I'm not sure but I think it can work with CDMA or GSM, hooray for global WiFi!

I wouldn't count on LTE on Sprint just yet. Hesse denounced it last week; however, Sprint, Clearwire, Google, Time-Warner, and a couple others purchased Spectrum not only in the 2.5 GHz, but the 2.3 GHz band also. So the bandwidth is there and, in the past, Hesse has been quoted saying they can easily switch to LTE if need be.

Thanks for the info.
I think the most important thing in the article is that LTE can happen if necessary.
Sorry for getting off topic.

Is it possible to modify evo's 4g to pick up clear's signal and use both?

Is there anyway to modify our wimax to receive both Sprint and clear's signal? It would help a lot of people out

I thought Sprint already uses Clear's signal? They are using Clear's network for it.
btw, the Evo's autocorrect fails to recognize the phone's name

Lolz just noticed the error in the title. As for the clear signal deal yes and no I have a clear tower no less than one mile from my house but I don't get wimax in my house hence it doesn't recognize clear's network so sprint uses there network but is on a different channel so Sprint has less area's with wimax.

doubt this is possible and btw clear uses sprint for 4g sprint owns a large if not all of clear that is how they have the 4g hotspot

Nope.
Clearwire and Sprint are 2 separates companies. Sprint DOES NOT own their own 4G network (well unless you count the 54% ownership). They sell Clear service like all other authorized resellers.
Also as another note. Clear is not on all Sprint towers. In fact most of thier site are separate for any Sprint asset.

This is correct. And if you've been following the news about these two companies, they are currently about as functional as a bad marriage that is simply staying together because neither currently has a better option.

that is why i was wondering if there was a way to tweek the wimax to pick up clear's signal it would make alot of people with out 4g on sprint happy i for one would be but so far this has become a debate on wether sprint runs on thier own towers or clear's. The questions still remains can it be done i would love a developers stand point on this

Sprint does not have any 4G towers. None. So no, there is no way to tweak your phone so that it can connect to both Sprint and Clear's 4G towers (again, because Sprint has none). All of the towers you are using for 4G belong to Clear and, I believe, you are not limited to a select number of theirs towers. Therefore, you are already picking up Clear's towers on their network. In fact, if you talk to Clearwire they will tell you that the Evo and Epic are actually Clear's phones that they are piloting on Sprint before rolling out their cell business. This is one of the reasons the relationship is so strained between the two companies right now. Sprint does not want to keep funding Clear because they are essentially funding a future rival - but it is hard not to because Clear needs money to keep extending 4G coverage.
Sorry for the long answer, but hope that makes sense. The answer to your question is....no

First time I've heard of this.
If its a new tower you may just need to wait for an update from sprint. Last time a bunch of people said they started getting 4g where they never did before. I wouldn't pay anything extra because you are already paying for it.

does anyone know by chance where to edit the realm on the epic?
there is no wimax menu using ##data#
or maybe this is just another fail of the dk28 early froyo release
edit: found the realm (hit view after ##data# (i kept pressing 'edit'))
nai isn't on the same menu for the epic however
still trying to figure that out - maybe NAP-ID?
NAP-ID is usually a non changing number like 2 or 4...but when wimax is connecting it shows the full realm
a bit confusing

Any downside to using old PRL's?

I'm not sure if everything on this phone works the same as my old s2, but it doesnt seem to. I fly to the same city 5 days/week, and it is outside of sprint service. On my s2 i just ran the 60675 prl which got me phenomenal speeds and no roaming indicated (using old alltel towers). I don't get the same speeds now with my s3, maybe 1/3-1/2 if I'm lucky. Using 25005 yields me no data coverage, 12124 and 60675 seem similar but 60675 is marginally better. Is there any downside to using it? I can swap back and forth if needed for my home area
Sent from my SPH-L710 using Tapatalk 2

The only thing to be concerned about is getting in trouble for using too much roaming data. Using an old PRL doesn't change anything other than possibly telling your phone to look for service on frequencies that may have changed. I would try to find the 00002 PRL for a relatively recent Verizon/Alltel only PRL.

I recommend PRL 11119. You can see my guide on changing PRLs if you need instructions or download links for PRLs.
Sent from my SPH-L710 using xda app-developers app

been using 60675 for the last year in this area, i don't actually use that much roaming data, i use wifi whenever possible, but if i'm in the car or away i need to have 3g access (navigation primarily). 60675 makes my phone think I am still in a home area which allows profile updates if i need to (especially if i am changing roms)
i used the Anycut method and it works great to change the PRL's but it is a lot of work trying to find them.

The downside would be that as Sprint makes new roaming agreements, your phone won't be set up to use the towers added by those agreements. It might also try to roam onto towers Sprint no longer has agreements to roam to, so you may end up with dropped calls. PRL lists won't affect your non-roaming coverage at all.

Im using 111115 corporate prl, its working good. I get dropped calls on anything else.

12124 seems to be working ok now

Prl 25010

So I flash the modded Prl 00001 at my work because I get no signal at all. I well I did the activation refresh with ##72768# and I kept seeing I had Prl 25010 and I usually had 25009. I don't know if it is any good or not. Anyone got this Prl yet? I kept trying to reactivate because I thought it never reset my Prl. I don't know if it's any better or not. Any one else know if it's any good?

Prl upgrades don't give you faster 3g speeds.

Agreed PRL 25010 for my device has given me nothing but problems. Starting around the 15th for me my device will periodically will not pass incoming calls to the phone nor incoming texts. All data works fine, all outgoing calls and outgoing texts work fine.
Also tested it on my EVO LTE and same problem happens.. Sprint support sees a high percentage of what they call blcoked calls (calls not making it to my device) and they cant explain it. 11% today, 25% on the 15th. She said anyhting higher then 5% is not good.
Ive already been told by another XDA member that PRL has nothing to do with it. BUT i think thats wrong. All this happened around the time the new PRL dropped. Call it a placebo affect but my data services and signal strenghts are lower across the board lately.
On both the GS3 and EVO LTE, and they both have the PRL 25010.
Taking it with a grain of salt tier 2 tech told me that they have seen a higher volume of issues related to call problems and data issues in areas with network vision and i told her i thought it was related to the PRL and she agreed, but we all know how those calls can go.
Prior to the update i had no service problems and was seeing the fastest 3G speeds ever (in dallas, tx and i get faster 3G and seeing more 4G LTE) I feel like im back on the old sprint network prior to all these updates.

After you updated the PRL, did you update your profile? If not, perhaps that may help.

Yup.. Today we did multiple data resets ##768 what ever the rest of the numbers are..
Did it twice and a few hours after each time im still not getting calls into my device.
I have done profile updates before and after PRL.

Are you in Baltimore area? That would be the only change in native Sprint service between PRLs.
What SID are you connected to? Check your ##debug# screen in the 1x section to find out.

Dallas, TX..
dont have the passcode its looking for when i put it into debugging. MSL code doesnt work.

Type in Sprint for the code. In numbers of course.
-- "Sensorly or it didn't happen!"

So after doing a lot more research i found out how to load a PRL to my device.
I was on PRL 25010 and am now back on 25009.
Guess what, my data speeds are back up to over 1meg on 3G. (yes that was a sarcastic guess what by the way)
I dont care how many times certain users say that a RPL doesnt affect speeds or connectivity. Call it a placebo affect.
Since 25010 dropped on us i have had nothing but crap tacular data speeds..
I was unable to get over 500k down on the old prl..
3 times now with the 25009 prl i have had 1.12 megs, 1.0 megs, and 975k down.. Ping times are also a lot better..
So problem solved now that i know how to go to an older PRL..

Very nice.. You are on 800SMR which increases coverage of course.
But as you can see there is absolutely zero differences between 25009 and 25010 for that SID:
25010:
SID: 22407 Sprint Nextel - Dallas TX; Longview TX; Lubbock TX; Monroe LA; Paris TX; Shreveport LA; Texarkana TX Prio:Same Roam:None
1X: S/476 S/526
EV: Sprint(0084:0AC0) P/475 P/650 P/550 P/575 P/375 P/75 P/600 P/325 P/175 P/225
25009:
SID: 22407 Sprint Nextel - Dallas TX; Longview TX; Lubbock TX; Monroe LA; Paris TX; Shreveport LA; Texarkana TX Prio:Same Roam:None
1X: S/476 S/526
EV: Sprint(0084:0AC0) P/475 P/650 P/550 P/575 P/375 P/75 P/600 P/325 P/175 P/225
The only recent change Dallas really had was the addition of 800SMR several PRLs back, even before the EVO LTE or S3 was launched. Probably what you are seeing is really Network Vision upgrades and such. Are you running a ROM that has the 3G/1X icon fixed? If not you could actually be on 1X instead due to some of the upgrades. And it is very possible to now only have 1X coverage in areas where you were roaming before. Enjoy the 800SMR... I'm jealous!

On my gs3 and evo lte (I switch back and forth periodically) I noticed a degradation of service from 25009 to 25010.
Both units stock. Non root.
Use the same server for speed test.
Same location. Either my apartment in my tv chair or office at my desk.
I do have mobile signal widget and network signal info to monitor my data connection and strength.
Several months ago my evo lte would get stuck on 1x. But that was several software updates ago. They fixed it. And when it happened I was well aware of it.
I'll enjoy my placebo affect and chalk up the better performance on prl 25009 to colder temperatures. Lol.

can I have my sprint note 2 work on Verizon

I'm sick of slow 3g speeds, my area got wimax so we are going to be last for lte (not that I got any wimax with my gs2) so I've been thinking of switching to Verizon... I'm still not decided but if I do decide can I take the phone with me or is it a waste of 800 dollars if I do it?
Sent from my SPH-L900 using xda app-developers app

I believe it's possible, but I'm not familiar with the process. And it definitely looks like it has some challenges from what I've read on some of the posts for going to TMobile, Boost, and so forth. I would definitely look at some of those threads to see what it involved.
If you did pay $800, you can probably sell it and get most of your money back.
As for LTE, I think if you got WiMax in your area, you'll probably get LTE sooner or later. Maybe you should ask Sprint when they plan to bring it to you market. I lieve in araa that didn't have WiMax, but I could drive fifteen minutes and get to areas that did. But we got LTE in the areas where I live and work. And most of the WiMax near me got LTE as well.
As for 3G with LTE, although the speeds are increased, in my area, it's not that big of a bump. It's only about .50Mbps, especially compared to the LTE speeds. I find I'm averaging around 1.2Mpbs on 3G, whereas before it was around .8Mbps.
Plus, you'll definitely want to see what the Verizon are getting, and maybe specifically on the GN2. Then you'll need to consider how, if any, change to how you'll use the GN2. Are you going to use more data, say more media streaming? I'm not that familiar with Verizon, but I'm not sure if they offer unlimited data. I know they use to. It's possible they may throttle as well. If there isn't a unlimited, then you'll need to know how much you use and how much that usage will cost on them.
I understand your frustration about the speeds. When I had the BlackBerry Curve for Sprint, which was on the iDEN network, the data speeds were so slow, I literally couldn't stream audio without a lot buffering; It was like being back on the 54.4k modem days on the PC. Going to the Evo 4G from that, even without the WiMax available, was like lightening fast. Sprint will bring LTE. It's just a question of when.

It depends on the frequency that the sprint note 2 supports. It has to have the 700 mhz frequency for verizon lte. I havent looked at sprints note 2 frequencys on this phone or not. Look into and see what all frequencies the sprint variant supports.

Lte will never work the sprint lte frequencies are 800, 1900 and 2500mhz and I'm not even certain current device's support 800 or 2500mhz yet as they won't be available until mid 2014 when iden is fully decommissioned for 800 and wimax is decommissioned for 2500

I like to break stuff!

The fact that your area got Wimax has no relation whatsoever to the order or timeframe that it will receive LTE.
For Sprint LTE info please refer to s4gru.com, specifically http://s4gru.com/index.php?/topic/212-network-visionlte-deployment-running-list/ in which they have basically ALL the LTE rollout information. Moreover, if you donate any amount (say $3) you become a sponsor and have access to maps with the towers that already have LTE etc.
