Question About CDMA & GSM - General Questions and Answers

Can a CDMA phone like the Verizon XV6900 or Touch Diamond work for AT&T. I am pretty sure the answer is no but I was curious.

Unfortunately not. CDMA phones and GSM phones are phones with completely different antenna hardware, and will physically not work with vice versa networks. I had a verizon Nokia 6015i that I thought had a working sim card slot and tried, but there werent even pins. Just because it shared shells with the Nokia 6012 GSM phone, didn't mean it had hardware capable of either network.
In the case of those phones in specific, unless they had a dedicated dual-antenna setup (in the likes of the new Blackberries and some Verizon-branded 'worldphones'), the phone wouldn't even have a sim-card slot to operate on GSM, much less the antennas. Some Verizon worldphones have dual-antenna capabilities, but only have quadband GSM frequencies, no HSPA/3G. I could be wrong, but last I checked, that was as possible as it could get.
For the two phones you've specified, the VX6900 is designed for Verizon Wireless only with CDMA hardware, and the Touch Diamond, while physically identical on the outside, is also outfitted with CDMA-only hardware even though there were GSM variants of the phone made too.

Sprint Palm Treo 700wx to have GPS?!?!?!

According to this internal spec sheet from sprint, the new Treo 700wx (which is identical to verizons 700w except it has double the RAM) the device will supposedly sport GPS?! I'm guessing that this will be nothing more than GPSone (as provideded in most CDMA chipsets by Qualcomm.) Here's the thing, I've heard numerous times that GPSone simply cannot serve as a navigation device, but what about Verizon's phone's that do GPS (such as the LG chocolate)? Aren't these phones using GPSone?
I hope they don't mean that GPS is optional as an external bluetooth device (but if so, why wouldnt they have marketed every single bluetooth enabled treo as "having" gps?) Let the rumors fly!

[Your Thoughts] ATT or Verizon

Hi,
been looking at the FUZE (ATT version of Raphael) and the touch Pro ( Verizon Version)
I currently have a contract with Verizon, and at the moment dont want to change it other than a phone upgrade and data plan, but the device...
lacks 128 MB of RAM (128 over ATT's 256) and doesnt have the G Sensor?!
This is rediculous, but I am pulled put over a barrel because I need The HTC Touch pro, Verizon doesn't use SIM cards either so I cant buy a fuze unlocked and use it under Verizon either. I'll pay the 15$ monthly but I honestly want my g-sensor and RAM
Your Thoughts? Anyone know if they offer an alternative with a SIM Card (Like their World Blackberries)
Laos
Verizon's does have a gsensor and a better keyboard layout then the fuse.
But no tv, lower ram, plus verizon is expensive etc..
Im only with verizon because i get 20% off my bill and i got my TP for free.
You also have to consider coverage. Do you know anyone that has ATT around you? You obviously know how well VZW is by you.
For me, both VZW and ATT are good around my house, but VZW sucks where I work and I get a full signal with ATT. Sprint is also good at both places.
As someone said, both models have the g-sensor. I'm not sure how much the lower RAM actually affects the device, so I can't speak for that either.
Also consider 3G. VZW has much more EVDO coverage than ATT's HSDPA, so check that out in your area too.
I've been very happy with ATT and the coverage around me. If you go ATT I would definitely flash a newer radio. The stock ATT Fuze radio was horrible for me.

Well thats confusing as hell, some say there IS a G sensor and some dont, but Honestly i can life with 128MB of RAM, I want my g sensor
I will stick with verizon, but i got one more question
the device has an internal GPS I can use for say, tomtom rather VZW Navigator, right?

Okay, im not sure who is saying that there isnt a gsensor. Im on my third TP and all of them have had one. Verizon packs their stock roll with teeter and opera that switches from portrait to landscape. It DOES have it.
And yes, it has GPS. I have google maps, live search, vz nav, smart phone tracker.....all of that on my TP. you should check out scroslers rom for it. Awesome!
As far as the RAM goes, I'm wondering how long until WinMo gets Microsofts ReadyBoost program availible. For those that don't know this program it allows you to use a flash drive (aka SDCard) as RAM.

Well, it could be a while, WinMo devices are notorious for having much slower card readers than regular Laptops and PCs, and to make it worse, the largest Micro SD Card (32 GB) is only at class 2, MUCH too slow for decent usage. However the 8 and 16 GB should be at Class 6. Which is okay. Still its best to wait until they solve the speed issue and have super fast 16 GB Cards so the card can still be used for ready boost with enough spare space for the high RAM programs themselves
Also, ready boost says ONE thing, EMULATIONS!!!!!!!
dont say silly stuff like it doesnt have a g sensor or ram. its the same hardware. it has a cdma antenna of course but it would be more cost efficient to leave the same internals rather than having a separate production line.

You dont know what you are talking about. The phone has less ram.....Even the form factor of the case is different. Almost every carrier has a different version with different hardware. Some have an FM radio chip, euro versions have a front facing camera, some are more rounded at the corners, the verizon TP is square. the battery plates are different etc...
The Verizon Touch Pro is bigger then the Fuze, but has TF3D Landscape and the Send/End buttons are illuminated green and red, respectively.
The Verizon TP also locks out the GPS chip to external software like TomTom (it works for some, doesn't work for most).
The Verizon TP does have less RAM, but it does have a G-Sensor. My brother works for Verizon and verified this by playing Teeter on it.
HTC's main reason for popularity with carriers is because they are willing to tailor their devices to a carriers exact specifications. Such as losing the FM Radio, front camera, RAM, etc...
Just like already stated, I would judge it by the network coverage in your area. With me living so close to Philadelphia, I have 3G coverage available from every carrier, so I don't have to worry about signal.
Which carrier?- Which ROM rather...
Greetings all, - hope this is posted in the right location, thought I would throw in my two cents regarding the question of 'which network'.
I just obtained a Fuze through AT&T- after 6 days of playing with it, I was extremely dissatisfied with the fact that my Tilt, through the magic of Kaiser Tweak can DL via HSDPA, (in some areas) but this is not available with the AT&T ROM installed on the Fuze.
I was too nervous to try flashing and potentially bricking the phone, so I sent the thing back for a refund. I would much rather drop a bit more cash for the international, unlocked version of the same device- without the sluggish, weighty crap programs and the bottleneck of a ROM AT&T has put on the Fuze.
Through the info posted here, I was able to drop the bloat, as I did on my Tilt- It was actually on a post here that I saw that AT&T had done this purposefully, to limit bandwidth access due to a huge influx of Iphones on the network. This may be hearsay, and I may be toatally wrong in my assesment, but the symptoms were definitely there. I could not even sit and browse the web in my house, while with my Tilt this has never been a problem.
Side note: When I returned the thing to a local AT&T store, the mouth breathing clerk stared blankly through me as I explained my dissatisfaction with the connectivity, and asked his opinion, as I noted he himself had a Fuze. He had no idea what I was talking about. To quote him: "That's way beyond my level." I chose not to pursue the issue further, though it seems that just through my reading here, I have learned more about this than the aforementioned AT&T employee.
My carrier decision was based purely on it's world wide coverage ability. I chose ATT.
In the past 2 months I traveled extensively through SE Asia, N. Africa and Europe. Having ATT has allowed me to keep intouch with work, friends and family.
Hope this helps
At&t Fuze all the way, i got it, it has more ram, it doesnt have all the Verizon restrictions on it, i like the angles back on the Fuze vs the plain verizon design

What are the restrictions aside from memory?
In my opinion
GSM > CDMA
If you go with ATT, you will have a GSM phone which, if nothing else, will have more resale value when you upgrade. GSM is the technology with a future, many manufacturers do not even make CDMA phones any more.
While the ramifications of this may never affect you directly, (i.e. moving to another country but using your phone with another carrier, or selling you phone to any GSM user worldwide) you might as well leave the option open.

buuuuut
despite that verizon took away memory, i still have yet to use so much that it would matter (i have att fuze)
at work and at home i only have 3g in certain spots of the house and office. when i do have it, it is hit or miss really. the only places i seem to get plenty of 3g is in big ol shopping areas.
others with verizon i know seem to have 3g every frickin where. streaming youtube, music, most of the time buffering-free. i am jealous thats for sure.
buuuuut
when i do have 3g it is really fast. faster than verizon. that is, if i can get it.
and i have tried several radios but i basically still have to hunt for that weak ass signal

OTECH F1 handset holds four SIM cards, enables you to live a quadruple life

So look, you feel pretty special toting around that dual-SIM phone, right? Being able to switch numbers and carriers as you hop back and forth between Germany and Amsterdam is fairly nifty, but you've been considering a daily route around the Benelux. Of course, tri-SIM phones aren't impossible to find either, but should you ever wander into France, Switzerland or any other nation, you'll be forced to pop one of those out and insert another the old fashioned way. Well, unless you can score an OTECH F1. This here handset -- which can only be found in the wilds of Asia right now -- actually has room for four SIM cards, and it's also packing a full QWERTY keyboard, 2.4-inch touchscreen, support for mobile TV, an FM radio tuner, Bluetooth module and what appears to be a 12.1 megapixel camera. Unsurprisingly, a price on this bad boy is eluding us, but if you're an industrious jetsetter, we're confident you won't have any issues running one down. Whether or not you want to, however, is another matter entirely... Engadget

Phone calling with GSM SIM?

Will Surface 3 make carrier calls or just Skype? Couldn't find any info...
Wikipedia has a nice comparison of Surface RT and Surface Pro models on the "Microsoft Surface" page, but long story short, there are no cellular variants of the Surface Pro. The ARM-based Surface RT line has cellular variants (for the second and third-generation models), but I don't think even those allow "ordinary" phone calls; AFAIK cellular connectivity is used for Internet (data) access only, much like with most other tablet devices.

rootable Tracfones still for sale? (also help me pick a phone?)

Hello, if i'm posting this in the wrong place please migrate this message somewhere better. Also I could post separate topics but i'm trying to wrap them into one. (if it's better to separate let me know - another board I stepped on toes for having "too many separate posts" that were lightly linked)
I'm trying to buy a Tracfone. Specifically a Tracfone "with 1 year service/minutes" bundle, actually i'm looking for two of them (me and GF) because her phone seemed to just implode recently for no reason.
Two places I know of having "bundling deals" are QVC and HSN, if there are others please let me know? I'm aware of shopcelldeals but those arent bundles, just minute-less phones usually.
One of my TOP priorities is finding phones that can root, yet searching for nearly every Tracfone for sale on either site keeps showing the same things - others asking for root with no success, talk of locked bootloaders, and similar. I am wondering if this is something across the board, if some manufacturers are worse than others, if some tend to have root methods show up later, etc. I can live without it for now, I just can't put certain cool things on until then.
If finding a rootable Tracfone is hopeless i'm probably shopping for conventional phones for BYOD but then no minutes deals with either a free phone or barely more cost obviously.
Makes little difference to be if 3G or 4G (despite the impending 3g sunset), CDMA or GSM, other than really trying to find Verizon or ATT Tracfones because of superior coverage where I drive. Actually ideal might be one ATT and one Verizon due to complimentary coverage. (where one is out the other usually is present)
The above probably already is a pretty short list of phones (if any at all) so not even sure if more details is needed, other than preferring a larger screen to make Google Maps more usable. (5-5.5" is nicer than smaller) That's honestly the most demanding application we are likely to need. Something with a replaceable battery preferred - note i'm not afraid of "non user replaceable" batteries that just make it hard/involve disassembly, have tools for that long as it's possible and there's a guide.
The fallback worst case scenario is just buy a pair of used Samsung Galaxy S5's one VZ one ATT and do the bring own device tracfone SIMs, but i'd like to see if there is something competitively cheaper since money is sorta tight. Any advice on anything directly or indirectly mentioned in this thread would be appreciated as helpful.
Actually, strongly consider used (as in pre-owned) CDMA (and specifically ex-VZW) phones; they can be purchased from many Amazon sellers, Wirefly, etc. Also, not all VZW customers trade in their phones (and especially not since VZW has the hypercheap Samsung Galaxy J3 that they are pushing to non-unlimited customers - my Mom bought one to replace her Galaxy Nexus, which I now have).
Once you have your ex-VZW phone in hand, order a SIM Kit from Tracfone via their BYOD page - https://get.tracfone.com/bring-your-own-phone/
While you are waiting for your SIM Kit to show, select your replacement ROM of choice *and* remove the old SIM - you won't need it for any of the prep steps. (You will need a wireless router with at least 2.4 GHz N support, though.)
For Samsung-based ex-VZW phones (which I suggest and which I will use as an example), grab the Universal Android Toolkit (current version is 1.5.6). While it is a Windows application, it is a "character mode" Windows application that runs windowed - no mousing here. The UAT supports features that ODIN flat out lacks; even better, you don't need to use that unique-to-Samsung "download mode", either. It doesn't just support flashing community ROMs/firmware; it can also restore supported devices to bog-stock (REALLY useful for phones you "inherit" from others). It even includes a mix of rooting utilities, and supports custom recoveries (it includes two versions of TWRP for the Galaxy Nexus, for example - with alternatives from the old CWM and Carliv's/Philz Touch (should you not like TWRP).
Some common misconceptions are about to get sliced and diced in this paragraph - so PAY ATTENTION.
First misconception - Tracfone requires a stock configuration. Not true of BYOP, and never has been. What firmware you run on your phone is YOUR business - Tracfone, in fact, could care less.
Second misconception - you have to start fresh (no porting). Patently false; you can port existing numbers to Tracfone BYOP just fine; I ported a lifeline number from Tracfone's Safelink Wireless division.
Third misconception - you can't port numbers from feature phones. See second misconception above; the number I ported was from a feature phone. (Safelink Wireless just started shipping Android phones itself; until Christmas of this year; the standard lifeline phone was a feature phone - typically from Alcatel, and connected to T-Mobile's 3G network.)
Last misconception - Tracfone uses a weak network backbone. While that was certainly the case with T-Mobile's network (which is still used by Safelink's feature phones), the LTE side of Tracfone (and Safelink's Android phones) is driven by Verizon Wireless - which is as solid as it gets in most of the US. As VZW predecessor company Bell Atlantic Mobile used to remind us in their video ads, a cell phone is only as good as the network it runs on.
Some surprises about the Galaxy Nexus in particular - first off, it doesn't support SD cards - at all; by that, I mean there is no way to physically mount them. (Therefore, don't even think about that option.) However, basic storage is capacious - out of the 29 GB of total storage, only 3 GB is used by my chosen firmware (PureNexus 7.1.1 for Galaxy Nexus) and GApps (Dynamic 7.1.1.) For that reason, I therefore have LOTS of room for files and apps (especially apps) - and without getting hamstrung by lack of basic storage space. (All too many devices compensate for that lack of basic storage by using SD cards; however, the tradeoff and hamstringing comes into major play with Lollipop and later, as they normally don't let you run apps from the SD card - that is why workarounds like APP2SD exist.) That capacious storage also covers why it's still supported - and especially why the Android community is still writing new ROMs for it, despite the dual-core TI OMAP CPU. (That's right; I did say dual-core.) In general use, there is surprisingly little bog in the GNex - even compared to a more modern phone such as the Samsung S7, let alone the J3.
