Hi,
I have a HTC Desire S which I bought Sim Free and am currently using a Vodafone UK SIM. I notice that a lot of my calls whilst on a HSDPA signal or even EDGE seem to be routed to voicemail even though the setting is disabled and I experience data blocks. Even though I'm shown I have data connectivity I cant use data and calls wont connect.
I was wondering whether you would think this is a SIM or a phone issue. I have had this on two Desire S phones and when using the SIM with a 2G only phone I don't seem to experience this problem. I'm in an area where there should be great indoor and outdoor coverage and the provider has no reported issues at the moment.
I think the problem is with network...
As you said with 2G you don't experience any issues...that proves the point...
I would suggest use only 2G (GSM) mode rather than edge...
until network improves...
Also that would give a better battery life ;-)
I too had a few calls go to voicemail when I should have had signal to receive calls, on t mobile uk, suspect that it's as the signal strength seems to fluctuate sometimes which I have seen, especially when using wifi And/or data.
Although not happened enough to be a really a massive problem.

Yes, like vampire36 said, the problem is in the EDGE & HSDPA network.
Try using 2G for a while with EDGE & HSDPA are closed for a few days then report back.
Hope this works out for you
I'm also on vodafone uk and I haven't had this issue, I'd say call the support line (as foolish as it sounds) as this isn't a problem I have had at all :/
But for the time being just stick to 2G so you can receive calls and such

Thanks for the tips. Vodafone have told me that there are 2 masts down serving my area so there isn't any 3G coverage and when I do very rarely get on HSDPA I experience data blocks because of the insufficient coverage. Even on 2G there are coverage issues because of these masts so now at least I know where the problem lies.
Has been an issue since February and this isn't rural countryside we are talking about but literally on the edge of the City of London! At least they've halved my bill till they sort it out.

So I know all the issues with older 2g sims affecting speeds, I called tmobile, and they said that I was in fact registered with a 2g sim, so I had them activate the sim that came in the box, but I have no improvement in speed. I'm still getting nowhere above 2mbps, most of the time around 1. I know I have a 4g data plan, they added that when I got the phone for immediate activation, not next billing cycle. Even in areas where my old mytouch 3G slide got 4 mbps on the 3G HSPA network, I can't get much above 2 on the HSPA+ network. What gives? If the new 4g sim and data plan aren't working, what's the issue here? Anyone else having issues?
Are you sure that you're connected to HSPA+? And, even if you are connected with good reception to a HSPA+ tower, that doesn't mean that the tower has good bandwidth backhaul. If its a low traffic tower, T-Mobile might not want to pay for a large amount of bandwidth for it.

I suppose I can't be positive, but the icon says 4G. Although I've never seen a 3G icon, only G, 2G, and 4G, meaning they probably just replaced the 3G icon with the 4G icon since the phone can't technically display a different icon for HSPA and HSPA+, can it? I've never seen a 3G icon so I might just be connected to 3G. But even in populous areas, like downtown, at night, I top out at 4, MAYBE 5 mbps. I've heard people getting 4 or 5 on a bad day, 7-8 average and 10-12 if they're lucky. I'm wondering where that's at, maybe it's a flaw in the stock rom and an AOSP or other custom rom would be better. I seem to remember having bad speeds on sense on my Slide too.
During data transfer, I went to the about phone>network menu, and mobile network type reads HSDPA and then reverts to UMTS after a period of inactivity. It does not specify HSDPA+ though, it just says HSDPA. I understand that the 3g and 4g networks on tmobile are technically one and the same, HSDPA+ is just an advancement of the 3G technology, but I'm wondering if something just isn't clicking and the phone isn't taking advantage of HSDPA+. I checked the coverage map, and the entire region I live in, minus a few rural areas, are supposed to be covered by 4G data.
I have a LG Nexus 5 and i have a strong LTE signal in my area along side HSPA+ if i make a Phone call LTE drops and HSPA is activated while the phone call is over it goes back to LTE in 20 seconds or so.
However if i use data while on HSPA+ mode it seems it wont handoff to LTE seamlessly
Like if you're on Verizon using 3g streaming consistently (not pandora something consistent downloading/upload like tunein radio) it would secretly bump you back to 4G LTE without any problems and stream would continue without even you noticing
T-Mobile however on the other hand doesn't until you stop the data usage and then it bumps back up to LTE
test it out download Tunein radio and stream a station make sure you're on HSPA+/HSPA then while streaming go to a location with like full or best LTE signal. (I went to the mall and drove right under the tower and phone still insists HSPA+)
not sure whats going on here? the Network not telling the phone to handoff? or some internal network issue or an issue with my nexus 5
by the way i am stock android 4.4.2 no root or recovery or whatever
So my question is is there a way to fix this? or is this something i need to email John Legere about?
I have similar issues but for Verizon losing eVDO and going to LTE is probably because EHRPD is making the switch more seamless. However, when my phone switches from HSPA to LTE I drop down to GPRS for a few seconds.

Just wondering if this happens to anyone else. My N5 was originally on Sprint but just recently switched to TMO. I have noticed that when on the TMO network my phone will drop to 3G whenever I make or receive a call. As soon as the call is over it switches back to LTE.
If I put my Sprint SIM back in and use their network it seems to hold LTE while on the call.
This is not scientific and am basing this observation from the network signal indicator on the top status bar. And as far as I can tell it isn't affecting performance. More of a curiosity at this point.

this is how its supposed to work. phone calls cant go through the lte signal(in this case, with tmibile) to the phone, so it drops to 3G(H).
LTE in it's current implementation is a DATA ONLY service so when you make voice calls it drops that connection and connects the call. Since 3G is Voice/Data it shows the 3G/H connection available to you at that time. When you hang up it goes back to LTE.
With Sprint it uses CDMA so theres no simultaneous option with that so LTE is kept alive in order to deliver data at the sametime.
All expected behavior as already mentioned
Thanks for the info. Makes perfect sense how that is explained. I am rooted and cleaned out some apps I don't want. I'm particularly careful to not mess things up and noticed the change in behavior on TMO. Wanted to make sure something I hacked for Sprint didn't FUBAR the connection.

I noticed this too on ATT.
When in calls it drops to H .
Thanks for the explanation

It is called CSFB (circuit switched fallback), which will soon be replaced by VoLTE (Voice over LTE), which will be a plain and simple SIP-controlled VOIP call using LTE as carrier. Not sure if current phones can and/or will be upgraded to be able to do VoLTE, or if todays LTE handsets are stuck falling back forever...
Is there a way to see and change the LTE BAND that my phone is on? Rogers support aws, 2600, 700. So I was wondering if I could manually change between them. The S5 has that option in the hidden menu, so I'm hoping I could do the same on this one.
Thanks.
The phone choose the band himself, if he don't find bands authorized by your phone company, he can't use them.

That's as far as you can get in telling it what network to operate on. It won't let you select specific bands (at least not stock). Mine was set to 'TD-SCDMA, GSM and LTE' out of the box (international version) and since I don't plan to use my phone in China anytime soon, it didn't make sense for the phone to waste resources searching for a TD-SCDMA (China's homebrew 4G) signal. Haven't noticed much improvement to my LTE signal though, still the weakest radio I've seen in a 'flagship' in a while.
Thanks.
I am also on Rogers.
Does that mean when I am on the phone, it will revert to EDGE instead of 3g by using the LTE-edge setting?
I have major issues with reception on this phone.
LTE Works Fine but the 3G/H+ signal is awful, absolute disaster on this phone. It is extremely, extremely weak. And I lose coverage often and over 50% of the times my calls go straight to voicemail because Rogers uses 2g/3g for calling. The phone can't drop back to 2G or 3G in time to receive calls when on LTE
Rly frustrating. Have tried playing with all the settings.
Same issue

I'm having issues with 3G H+ too. Dont know its CM issue or not coz I had nice H+ signals on Color OS...
Can't even use internet data. most of the time network drops after using internet for a bit.. Network just suddenly gone and after that it comes back with no internet. Internet comes back online after a while...
Really worried.. and annoyed coz can't seem to find any solve for this. Even Mahdi rom had this issue..
Hi all,
I am using a Z5 E6853 Premium with t-mobile LTE APN settings fast.t-mobile.com - LTE seems to be working, but drops when I call.
My wireless reception is dropping every once in a while as well. Anyone else experiencing this issue?
Not sure if it has to do with the APN settings... I am testing out the other tmobile APN (epc-t-mobile.com). My preferred network setting is LTE (preferred) / WCDMA / GSM
Any help would be great, thanks!
LTE drops during calls because the Xperia Z5 line is not certified by T-Mobile for VoLTE (and probably never will).
As for the signal dropping I experience much of the same, my signal is mostly in the -90~-100dbm (which is terrible signal, i think contributes to battery drain).
I had a chat with a t-mobile rep and nothing they tried worked, so i'm not sure what exactly is the issue there.

That level of signal is actually acceptable for LTE and my old m8 reported similar dbm, but was tuned so it displayed more bars. Wish SONY would give us a dbm adjustment or someone knew how to adjust it... I do think it is tricking the radio to actively search for 'better' signal leading to battery drain
I'm in the exact same boat, hoping someone has a fix otherwise will need to get a new tmobile specific phone..
I had to switch to straight up google voice for all my calls...people get dumped straight to voicemail for me ..
