    Did you actually get dropped calls and/or slower data speeds? Carriers and manufacturers have been known to tweak signal meters to make their signals report better than they are. I suspect you were getting the exact same signal, but the MV WHITE ROM was reporting a more accurate reading than the T_Mo ROM. On I-Phones you can dial *3001#12345#* to get the exact signal reading by db instead of a made up one by the carriers. I wish I did know how to enter test mode to do that on a Windows Phone, if that's even possible. When I first went on the AT&T network and still had the T-Mo ROM loaded, it always showed 5 bars and was very suspicious of the readings, just can't prove it. Now I see anywhere from 3 to 5 bars. That said, since the MV White is a South American ROM, your WIFI signal will read lower. I have seen that myself and it is due to South American routers having double the output power ours do and the ROM looks to have been adjusted for that.
    I just flashed to the Latin American ROM this week (thanks Munter2 for your post in another thread with the needed links), and I'm seeing the exact same behavior. I'm seeing lower bars, but overall the behavior is the same. What I mean is at work, for example, there are spots where I could get a signal (at my desk, fortunately) but I didn't have to go too far into the interior before I lost signal. While the Latin American ROM showed fewer bars than the T-Mo ROM where I got a signal, I didn't seem to lose a signal any earlier. Likewise, I was trying out an AT&T MVNO (Consumer Cellular, not Cricket), and also saw constant full bars with the T-Mo Rom, but now see 3-5 bars with the Latin American ROM. I think the T-Mo signal meter is....optimistic.

    I have to respectfully disagree. The general t-mobile (and roaming) coverage around my area is decent. A lot of 2g coverage, but I lived with sprint for nearly 15 years. However, I live at a secluded lake, where Sprint, Verizon, AT&T, and of course T-Mobile don't have coverage. Staying with t-mobile is really my only option to have "service" at my house...
    Certainly there are cases where WiFi calling can be useful, and there are even locations I suppose where T-Mobile's service is not only perfectly adequate, but even better than the alternatives. Although I'm curious, if you have broadband (for WiFi calling), would a microcell also be an option that could increase your choices in carriers? Might be more complicated and/or expensive, though.

    There are no "micro cells" or femtocells in the TM vernacular. You can buy or sometimes get a Cel-Fi booster, but these are not broadband based like microcells. I've been a WFC advocate for seven years. Problems? Yes, sometimes the phones, sometimes the network, but the premise is unassailable. I've been in Camel Anus, TX, at a coffee shop. No TM signal, no problem.

    I'll address both of you:
    I could get a microcell from any of the other three (which is what I believe mrpunny was meaning), but the added cost of their plans makes that option not worth it for me. Especially since TM's wifi calling does a more than ample job, without having to add yet another piece to my network (which is a paltry 6d/.5u). It's like I live in a radio signal black hole. Cable company doesn't come there, and I had to cut down a couple trees to have satellite tv service. Cellular picks up less than 1/2 mi from the house (2g att) and at 5mi (where I spend the most of my time when I'm not home) it's TM LTE.

    One size does not fit all. WFC is way more preferential that femto cells. You don't need to have access to a broadband modem/router. "Hello, I have this device here that you've never heard of and I can't get a cellular signal, would you mind if I plug it in to your network?" BZZZZZZZT!

    Fair enough. From your previous post I just wasn't sure what other options you had looked at. I agree in your case it sounds like T-Mobile's WiFi calling is the best option for getting service at your home.

    In one sense, it's the only option. Whether TM sends you a Cel-Fi booster or not, is beside the point. Said booster is not the same as a femtocell, the latter requiring a broadband connection.

    And so if you travel, you'll pack your booster? And even that depends on a one bar signal to work. I've been on WFC since it's inception via different phones. I know just about everything there is to know about both the technology (GSM/UMA) and the marketing thereof.

    With WFC you can be anywhere in the world, on a wifi access point to broadband, and the TM system sees you as right here at home. What's not to love? No TM signal in Marfa, TX some years back. But the coffee shop has your voice and SMS connections waiting.

    WFC has been available to any GSM carrier for almost a decade. Why ATT has just recently picked up on this, no idea. Oh, wait, otherwise they can charge their customers more for roaming and international calls? Nah........

    Said ROMS are here along with everything your need: http://pgotze01.synology.me:5000/fbd...E&stdhtml=true Said instructions are here: [Tutorial] Unbrand (flash) Nokia Windows Pho€ | Windows Phone 8 Development and Hacking | XDA Forums The only ROM I recommend is this one: product code: 059T883, variant name: RM-893 VAR LTA MV WHITE. I'm sure there are others that work, but it has all the US LTE frequencies and works great. I tried a couple of others that wouldn't flash including the AT&T one. Microsoft lists this as generic for Mexico. Argentina, and some other countries down there also have carriers that use this as primary. If you have trouble with log in to Nokia to get the ROMs, make sure you have replaced the 3 instances of the file in your new Nokia folder with the one you extract from the RAR file.

    Thank you...I said :)

    It's nice to have options, and all things being equal, I agree that it's better to have the option of wifi calling than not. However, if you literally only lack coverage at home, then a microcell or wifi calling are potentially equal, assuming that the carrier will give you a microcell for little or no cost. Ahead of either of those, though, I've come to prefer a carrier that offers broad coverage with low frequency spectrum for good in-building reception. (And while it can be a little clunky, there are VOIP options like Skype or a service like CallCentric that will provide calling over wifi that doesn't require low level phone support, and thus don't limit choice in phones. But I would consider that more for the occasional workaround rather than regular usage.)

    Now that said, if T-Mo continues on their current path, I think they have the potential to be an amazing service in a couple of years. They're supposed to be converting their 2G network to LTE over the next year, and more importantly, they're currently acquiring chunks of low frequency 700A spectrum. Hopefully they'll also be able to get a significant amount of spectrum in the upcoming 600MHz auctions. That low frequency spectrum will really help in-building reception and should also improve coverage area, meaning that T-Mobile's native network will be much more equal to the big 2, plus they'll have wifi calling working to help fill in the inevitable small gaps that affect every carrier to some degree.

    Well I flashed successfully and I'm discouraged to find that when search for my carrier it only found the 4G option not the LTE !! That I could get with the T Mobile firmware tell me that this so called International firmware isn't so international !~ And the kicker Net sharing works fine but i can only get a 4G signal and it's only getting 2 bars out of 5 !! WOW all that for nothing !!

    Are you on the T-Mobile Network? Are you using the MV White ROM? If you are,the option menu will show 4G but when 4G is activated if an LTE signal is available you will receive the LTE signal. The signal strength meter will show less signal with the Latin American ROM, but you will actually receive the same signal as the T-Mobile ROM as carriers "adjust" the the signal strength indicators for their own purposes. Run a few speed tests to see if your speeds are actually slower.

    Yes, there is no assurance that X bars on any two phones or any two ROM's mean the same thing. "They" can adjust that into the firmware. It's just like any meter in any electronic system; add/remove resistance in series or parallel and you can show anything you want.

    Yes, to another poster, as TM ramps up all the low frequency stuff (with new phones) it will finally be the equal of the Big Two in building penetration and distance.

    With the T Mbile rom when i went to search for Network in my Area ( Eastlink is the provider ) it actual said 4G/LTE) and I coudl pick and choose -and the speeds from tests were considerable with the rom you mentioned ( I followed everything to a science ) I currently am only offered 4G in the selstion ..Yet it does say LTE in the above let top ( so you could possible be right ) although it did flux from a 4G icon , to an H to H+ as well .....the bars are currently stable at 3 /5 so thats no issue ...Internet sharing does work as does Blu tooth and wifi. So no hiccups. I wanna say thank you for the post it only took a mere 30 mins to flash the reading the tutorial was longer but I'm very satisfied thus far ..I appreciate if very much Munter2. I bought this unlocked beast on ebay with a cracked screen ..purchased a dead in the water lumia for 30 bucks swapped screens and been running in Nova Scotia , Canada for the last 3 months and have loved it. So unbranding this Lumia 925 was not an issue for me ..thanx for making it possible...BTW my Provider is the sister company to T Mobile in the United States. EastLink Wireless only runs on the 1700/2100 frequency hence the reason i sought ou tthe Lumia 925 on T Mobile as the unlocked AT&T Nokia Lumia 820 i had could not give me LTE speeds or mostly connected to the network

    Speed test shows 56.50 mbps and 20.23 upload so thats pretty decent in my area so the LTE is working correctly on 3 bars out of 5 ..considering I only get about 45.26 mbps and 7.76 on my wireless ( My home net is 80 mbps and 8 upload ) wireless is usually a bit higher ( I don't expect it to be at the speed of the full range 80 ) but I'm satisfied

    The AT&T ROM won't flash to a non AT&T phone. You will need to flash to a South American ROM. Check post 24 of this thread for one that works, been using it for a few weeks and it's great on AT&T's network.

    @Munter2 have any ideas why i can't get my Microsoft Account to update ( up to date ) sync to my phone!! I was fine until i hard reset while on Developer Preview. Did the step up and couldn't get the account to sync. Message I get is OUTLOOK error Not Updated: We can't sync right now. But you may be able to find more info about this error code atwww.windowsphone.con last tried 6 mins ago. Error code:80070490.

    I have made sure the Calendar and clock/time zone was correct ( took it off Auto ) shut back ups completely off ....Unchecked Content to Sync email check box on the actual account even shut off Sync my setting!! - I read all the above for work around to no avail. I have soft rest and hard reset! The only time i was successful was when i used another Email ( Hotmail ) when setting up and used what I normally use as my primary MSN account ( accounts/billing /game history ) as OUtlook secondary and that both finally syced come the morning after many failed attempts through out the night . Now i could have left it that way but because the Hotmail wasn't the account I've used for over 10 yrs or more with Microsoft - I wasn't able to bring up my content /purchase history so i had no choice but to hard reset again and well now it's been 2 days and still my MSN account will not sync stand alone as the primary !! very pissed !!!!!!!!

    I answered this on another thread, but probably wasn't very helpful. I know Microsoft is trying to push everyone to outlook.com and away from MSN and Hotmail accounts so don't count on quick support from them. You might give it a day or two more before you do anything as there have been power issues here today. Here is like 4 blocks from the Microsoft Data center that runs their cloud stuff. Of course they have plenty of generators over their, but it just makes me wonder when I've seen a high voltage power line switch across the street pop open twice this morning. That thing is loud too.

    So flashing it to the South American ROM will get me Cyan, and I'll lose WiFi calling (I'm not even using it on T-mobile, so I sure don't care).

    I assume I could still hope/wait for the T-mobile update, put my old Sim in, and update it over WiFi, as an alternative option? My family is all on T-mobile, so this actually holds some appeal for me (i.e. if my wife needs a new phone, and I am willing to let her use my 925 - but that means I have to use my iPhone 5S :( )

    I'm assuming this process is much much easier than the horrible android unlocking/rooting/flashing I've done in the past! S off? S on? What?? Arghhhhh!

    It doesn't matter what SIM is in the phone. It is totally dependent on the ROM loaded into your phone as to when, if ever, you get updates. Flashing to a different ROM with the Nokia Care Suite is the only way around it. As long as you follow the directions from the link in my previous post, it's very easy and takes less than a half an hour with most of the time spent waiting for the firmware to download. Just make sure the SIM is out of the phone during the process and you do the master reset after the flash.

Although this is my 2nd flashing of my Lumia 925 again My main Microsoft account still refuses to sync and this time instead of doing a fresh install i reverted back to a previous date ( so that the apps and settings were the same before the flash ) and Now I get a big list of a screen

    Hotmail error

    MMS works on both Cricket and T-Mobile, Internet Sharing does not. But the switch is enabled and your carrier might support it. Also this ROM does not have the APN settings editable, you'll have to use Access Point to enter the settings

    Why not add internet sharing to the does not work list as well. BTW there are no known firmware for the 925 that would support Visual Voicemail on Cricket
