So I'm wondering if there's a way to speed up the handover between wifi network & cell network when walking between connections (mostly during phone calls). Searched a bunch of threads about this and it seems to be a common question, but nobody seems to have a definitive answer. Is there a way to tweak either phone settings or ROM settings (Octane v3.0) to make the handover seamless? I just hate dropping calls when moving from a wifi network to an area without and the phone switches automatically to a cell tower. Thanks in advance for you responses/help in this.

Hello,
I've noticed that most of the well knwon Samsung Secret and Dialer Codes are not working on the new Galaxy Tab 7.7 P6800. Are there known solutions for this? Other codes that are working?
I noticed the same thing.

Yes all known USSD/MMI Codes are working on GINGERBREAD on my SGSII but not on SGT7.7 with HONEYCOMB. I think its cause HONEYCOMB
I have found, that some of the codes can be used with the App "SGS Secret Codes".
Since the codes are working, I think, they are filtered by the Dialer App.

Only 2 of those codes work, the one to check the imei and another one which I font remember, the others nothing. Im looking for the one that shows the frequencies and you are able to enable/disable then. I wan to check what frequentcy my tab picks up while running T-Mobile sim

Funny thing, i tried downloading the sgs codes app and now i have access to the frequency selector i have set up the tab to work on 1900mhz now i have to try and see if i can get full 3g+voice on tmobile. Will report back.

Maybe we can get in touch with the lidroid developer. I would like to have some other codes, like *#272*IMEI#. I will try it next week.
How about the lcd test menu?
Ok so while taking my dog out i took my tsb and wanted to see if it would pick up 3g with tmobile. and the result is, no. See the following and you will notice that 1900mhz is selected:
View attachment 888880
View attachment 888881
View attachment 888889
View attachment 888890
The first pic shows the tab connected at 1900mhz but if you look at the bottom right hand corner it shows as running on Edge. So maybe its picking up Sprints signal and Tmobile has not rolled out the 1900mhz over on the east coast?
EDIT: please let me know if you are able to see the pics. Everytime I go into the thread the pics are not coming up

Nah, you're not going to be able to pick up Sprint anything, even if they use the same frequency bands; totally different technologies CDMA vs GSM/UMTS. Actually, believe it or not, UMTS has a lot in common with CDMA, but it's still not compatible. CDMA, specifically EV-DO, uses 1.25mhz spectrum channeling for it's available bandwidth. Also, it's simply a data stack, hence the "DO" in EV-DO (stands for Data Optimized). Modern CDMA networks still rely on a 1xRTT network for their voice stack. Because both stacks are separated by two different technology standards, the phone device can only really use one at a time. It is theoretically possible to do both, but that would require essentially two modems, one dedicated for voice, and one dedicated for data, but cost and complexity likely make that prohibitive. Instead, it's cheaper for CDMA devices to incorporate a modem that switches between the two stacks (voice/data) on demand, while keeping the idle stack on hot standby. That's why CDMA phones can't do data and voice simultaneously (easily).
UMTS (AKA WCDMA, or Wideband CDMA) on the other hand, is a whole different ball game. Because UMTS is technically a CDMA based technology, it also utilizes code division multiplexing as opposed to the time division multiplexing scheme used by legacy GSM. However, that's about where the similarities end. UMTS uses 5mhz spectrum channeling (4x the channel bandwidth of traditional CDMA/EV-DO!). Also, both voice and data are separated logically, instead of physically, by using dedicated slices of that 5mhz for their respective tasks. Essentially, part of that 5mhz channel will be dedicated to circuit switched voice access, and the remaining channel bandwidth is dedicated to packet switched data. In this way, a single modem can be easily used to perform both voice and data simultaneously because both protocol stacks are rolled into one nice neat package.
To draw an analogy, think of CDMA like having two plates of some Mexican food. One plate has your veggies (like your beans and rice), and the other plate has your meat (like your beef, chicken, or pork). By protocol standards, you're only allowed to eat from one plate at a time.
With UMTS, you're basically taking all those same ingredients, and rolling it all together into a burrito!
P.S. I've tried enabling the 1700mhz band via the service menu, and attempted to get 3G signal on a T-Mobile SIM, but no luck. No 1900mhz T-Mo 3G in the Washington DC area either btw.

We all know that we cant get 3g on 1700mhz with tmobile only edge thats why i wanted to see if enabling 1900mhz would work. But i wonder how i am picking it up if tmobile has not implemented it here on the east coast, guess ill just have to keep waiting until they do. No point in calling tmobile and ask them as i am sure they would not have any clue.

Having looked at your pictures there, it looks like you're connecting on GSM 1900 (which T-Moblie does support). This is 2G, not 3G/4G. If it were, GSM would be replaced by UMTS or something. See my pic in the attachment.
Also, see how it says WCDMA 1900 Band 2? It'll tell you if it's using UMTS/WCDMA or not.
Hi guys, I have problem with my network connection also my 3g does not work anymore, I was playing with my phone with some secret codes like a ##72786# on my epic 4g touch sprint phone flashed to metro pcs and now I have no 3G service. In the setting menu under network status say Sprint. How can I get my 3g back?. The mobile net. 3G is on and the wifi is off. I need to change the network to metro pcs in the status setting and how can do that? Thanks for your help and sorry for my bad English.
Running ICS OS.
Can you re register your network by scanning network operators? If not you will need to Google APN settings for your network.

Does anyone know if it is possible to get a "WCDMA/LTE Only" mode on the Nexus 5?
I basically want to stop the phone dropping to 2G. Recently LTE has been made available here and before that I used "WCDMA only" and it worked fine but that is no longer a viable option since I want to use LTE.
Thanks in advance

I do, but I can use 3G to do this. I mean I don't want it to drop to EDGE.
The reason is, in Ireland the network provider Three does not have a 2G network and roams to Vodafone when it 3G isn't available. It then will not automatically change back to 3G. You need to manually select the Three network again.
you have no option then. you have either lte only, which gets you data and no phone calls, or you have lte/gsm. on gsm/lte, itll switch to whatever is your best signal.
Wouldn't it be easier to choose the operator manually?

It still jumps to vodafone when there is poor signal, even when manually selected. If there was a way of forcing it to stay with one operator or disable roaming completely, then that would do but there doesn't seem to be an option.

Not on the Nexus 5, as far as I'm aware. I think it just disables data anyway. I need to be able to disable roaming completely or restrict to WCDMA and LTE.

When looking in SlimKat (admittedly not stock), it is @fergietime suggests, national data roaming and would still allow the phone to roam to another operator when there was no signal on the existing operator - just with no data. However, I am not seeing a problem with that. It only roams nationally when there is 0 signal for voice on your operator?

Yes, but it happens me quite often due to certain places that I pass through. My operator does not have a 2G network at all so roams once it drops below 3G. The main problem is, I need to manually search for networks and select my network to get it back to 3G/4G. It's a network issue that Three Ireland refuse to acknowledge. It has been happening for 4 years at least. I am just looking for a workaround.

I see.
I am also on Three (UK though) so also have no 2G coverage. and yes, when it fails over to 2G (Orange in UK) it is a pain to get it back.

It's a very frustrating issue. It actually NEVER jumps back to Three and it changes to Vodafone nearly every time I go inside a Tesco or somewhere like that. I then have to search and wait for it to find networks so I can select Three. The only time it seems to work correctly is when using a device bought from Three or a Three rom, which obviously for the Nexus 5 doesn't exist. And even then people complain about it so it's a bit hit and miss.
Does anyone know if it is possible to add a "WCDMA/LTE Only" mode into a rom?
Hi, I have a Verizon Edge that I am using on T-Mobile, I am getting LTE and everything but every time I receive or make calls my data stops working, any help to resolve this problem will be greatly appreciated. Thanks in advance.

T-Mobile uses VoLTE (voice over) and it must be supported by software in its phones, if it isnt, it will switch to 4G (H/H+). Does the VZW NE support H/H+?

Yup, even though Verizon LTE phones are unlocked out of the box they are not smooth sailing most of the time. They mess with them somehow to make some things inconvenient. You'll have to search around for the solution by people in the same boat as you. That's what I had to do when I was using the Droid Maxx on T-Mobile.

My advice to you would be to not limit yourself to searching only those with a note edge but instead expand your search to anyone using a Verizon LTE phone on t-mobile. It is usually something similar that is causing the problem therefore something similar that will resolve it.

The Note Edge only has 1 antenna and on Verizon phones you have to install and subscribe to Advanced calling in order to get simultaneous voice and data. And since Verizon's VoLTE requires Band 13 I believe, you are most likely going to be out of luck.
