EDGE only, no HSPA with FreedomPop GSM SIM - Droid RAZR M Q&A, Help & Troubleshooting

XT907 on stock KitKat ROM (rooted).
I get EDGE only, no HSPA with FreedomPop GSM SIM. I've configured APN as described on their site.
https://support.freedompop.com/app/answers/detail/a_id/2670/~/activating-your-phone-gsm-sim-card
I have a good strong signal. I assume it connects to AT&T towers. Even if it were connecting to T-Mobile, I'm in a refarmed area, so I'd think HSPA should work.
Any ideas?
UPDATE: Problem solved. Needed to force UMTS in settings because it defaults to GSM.

AT&T 3G resolution

Okay, so I've been trying to figure this out.
When I get the tablet, I was in Florida, and the 3G worked fine. No problems whatsoever. Now that I get to my home in the NYC area, the 3G doesn't work at all.
I've tested with 3 different AT&T sims and 2 different S7 tablets.
Here's what I found out.
Edge works. Edge will always work. The device has no problem initializing with the connection with the cell tower when GSM Only is set. After the device has initialized with the cell tower and has signal (Settings > Status > Mobile network state: Connected), you can switch to WCDMA (3G bands)
Data will work, but dialing out will not. This is because voice is a different channel than radio on 3G.
But if you remember, I said it worked in Florida. I believe this is because, in Florida, I probably didn't have HSPA (3.5G). I only had UMTS (3G). I have tried to disable hspa and try to get it to work on 3G only, but I haven't found a way.
Are there any AT&T users on 3G that would like to report their findings?

I replied to you a while ago over on androidtablets.net - but have you tried the Indonesian Froyo update? It includes a radio (baseband) update, which seems to have fixed all of the 3G problems I was having before.

[Q] 3g or bust? (GSM)

Any way of turning off 4g and enabling 3g while on GSM unlocked?

Changing to GSM/UMTS should turn off 4G LTE and read 3g/2g services from the SIM and APNs. For me, to enable 4g as well as GSM, I have to use *#*#INFO#*#* and select LTE/UMTS/GSM from the menu, otherwise setting UMTS/GSM from the standard mobile network menu puts it in GSM Auto (PRL) mode, which is just HSPA+, UMTS, EDGE, and GPRS frequencies. (3.5G, 3G, 2.5G, and 2G respectively). I have my Razr M setup with a Straight Talk AT&T sim for GSM and PagePlus on CDMA, service toggle works flawlessly after setting it up.
But yeah, if you go into the mobile network settings and change it to GSM/UMTS mode and set the proper APNs, you should get 3G without issue and the LTE radio should be off (since it only supports Verizon's LTE band anyway)

I've not used that rom, but you should still have access to the secret menu, Open the dialer and type *#*#INFO#*#* (*#*#4636#*#*) > Phone information > Scroll down and select GSM auto (PRL) it's the same thing, GSM/UMTS only based on the SIM.

WCDMA Preferred would actually be a better choice and is the default choice on normal GSM phones, GSM auto (PRL) uses either 2g or 3g and just chooses whichever has stronger signal, WCDMA Preferred will make it use 3g as long as there is 3g signal and only drop to 2g if it has to.

Yeah, but in my experience with using verizon global phones on gsm, trying to set this always changes itself back to gsm auto making WCDMA Preferred a moot option.

WCDMA Preferred actually activates the 4g HSPA+ and GSM Auto only connects me to Edge: 2 making both of these options moot :-/

Uhm... HSPA+ is actually 3.5G.. It's based on the UMTS 3G standard and is technically the same thing/catagory. "4G" is a marketing gimmick by AT&T and T-Mobile, they even had apple push an update on the iPhone when they started marketing it as 4g to change 3g to 4g on the phone. Although they did NOTHING to the capabilities of the phone. The phone does not differentiate between 3G UMTS and 3.5G HSPA+ as far as WCDMA/3G connections go, 4G should be referred to only on LTE, but carriers like their money. Remember AT&T used to tout the 'fastest 3g network' now they claim 'the largest 4g network' It's the SAME NETWORK, they just upped the number. T-Mobile actually offers a 42Mbps dual band HSPA+ network, whereas AT&T only has a 21Mbps HSPA+ network, both of them advertise as '4g' but they also have 4gLTE networks.
So in ALL technicality; their "4g" HSPA+ networks are ACTUALLY 3G networks... There is no way to force the phone to use only UMTS as it's the basis for HSPA being the 'same' network type. The only real 4G is LTE, which without a verizon SIM card, is disabled when not using an "LTE/CDMA" option.

We need more clarification like yours on the interwebs ^_^ thank you. Either way, my issue appears to be throttle and neither option allows me to get above 8 kbs download speeds.
Still a shame they need to be so crude about their marketing. And I tried so hard not to be a sucker!

Minor correction: AOSP and maybe stock (not sure...) do indicate HSPA+ in the status bar by changing it from 3g to H+
Also, technically LTE isn't 4g either, but it's the closest to 4g you can get.
IIRC it's ~50mbps ideal and ITU 4g standard is like 100. H+ is like 30 or 40. Of course, my numbers may be way off... It's something like that though
Also, there's no GSM/LTE option? Could've sworn there was one...

The stock rom shows H+ and next gen lte is 300mbps capable, current is ~100mbps. I have seen someone hit 45mbps on a droid 4. Course you won't see anywhere near ideal max. Hspa+ is 21Mbps dual band hspa is 42Mbps. As I recall they are working on a 1Gbit lte, but that will be a long way out. There is an lte/gsm option, but since the M doesn't support lte bands besides verizon, kinda useless. Lte sim will be lte/cdma verizon.
While on cdma my phone shows 3g for evdo and H+ for hspap. (I have pageplus and att sim straight talk on my M).

Gotcha.
1gbit? So you can burn up a 10 GB data plan in 40 seconds! YAY! I WANT ONE!

[Q] D802 Not connecting network

My new LG G2 D802 seems to only want to conect to GSM, if I have it set to any other setting like GSM/Wcda auto, or LTE etc it wont even connect to GSM let alone the other networks? To be clear i can use the phone set to GSM, but not when set to the other settings, just keeps searching for network
I am in New Zealand on Vodafone network which is
2G - 900/ 1800 MHz GSM, GPRS
3G - 900/ 2100 MHz UMTS, HSPA, HSPA+, DC-HSPA+
4G - 1800 MHz LTE
so I think the phone should connect shouldnt it? I am in 3G/WCDA coverage (not in 4g currently to try)
Any ideas?
the phone is stock rom, rooted, Xposed etc, Kitkat 4.4.2
Thanks
Edit, I just clicked network operators and searched and it came up with Vodafone Gsm which i have selected. So i take it my phone cant see a 3g network?
I think I have solved it. I went into the hidden menu and changed the modem settings to my carriers frequency instead of auto. So fingers crossed. II havedone a reboot and it is still working too.
So I had 3g for the day or so and then its gone again, I tried my wifes sim card which is on a different network and seemed to work, so i will get a new sim card for myself and hopefully be ok. my current sim card works ok in her phone, it just struggles to find 3g in mine for some reason.
Got a new sim card now but it still struggle to find 3g maybe because I'm not in a main town centre but I should still have service here as I am in there coverage area and my wife gets coverage on her phone
Tried updating to lollipop but problemremains. It is disconnecting maybe because of poor 3g reception but then struggles to connect to 2g again. Only solution to have working phone is ro have it set on gsm only all the time. Not good

AT&T & Verizon Sim

So Ive got both my Verizon and At&t sims working however I run into a issue when selecting Verizon as my data provider.
Sim 1 is Verizon (wont allow Verizon in sim 2)
Sim 2 is At&t
Select sim 2 for data and sim one switches 2 "31000" for calls and texts only which is fine. Sim 2 (At&t) handles lte, calls and texts no problem.
Select sim 1 (Verizon) for data and sim 2 (At&t) goes into "no service". Cant make calls, texts or anything.
So basically the only way to get both sims working is to use at&t for data. Problem is my Verizon card has unlimited data. The Verizon data works perfect whether I have 1 sim in or both.
Any ideas?
It's probably because AT&T has decommissioned EDGE service in your area. SIM 2 can only be EDGE when a CDMA (Verizon) SIM is in slot 1 and is being actively used for data. With two GSM SIMs you can have 3G and LTE simultaneously...but not with one CDMA and one GSM. It's a hardware limitation I believe, though I'm not totally sure as it could be a bug too.
Check the AT&T coverage maps to see if your area requires a 3G handset...if so, then your Axon will always show No Service on the AT&T side when Verizon is being used for data.
Yep thats it. At&t shut down 2g on January 1st this year. Thank you.

Was this limitation discovered through trial and error or is it actually documented by zte someplace. The limitation about cdma/sim2 edge specifically.

ZTE is pretty tight-lipped on CDMA for the Axon 7...originally they claimed they were going to disable it altogether until it got Verizon and/or Sprint approval, which seems to have not actually happened...so they've basically said nothing about it at all, except that it's shown on the specs of the phone.
But anyway, no...ZTE has not stated there's a CDMA-use limitation on SIM 2 for EDGE only...it's just that everyone has seen this occur through anecdotal experience...and we know for sure that simultaneous 3G/LTE is possible with two GSM SIMs so it seems that there is some issue that CDMA creates where UMTS cannot be received concurrent active data use on a CDMA SIM.
A while back I tried a tmobile sim and freedompop (on att) global sim. With tmo on 2g and fp on hspa, the tmo side was constantly disconnecting (I believe we discussed this in one of the other vzw threads). I came to the conclusion that it had something to do with the actual frequencies being used by both sims. Changing the tmo setting to 3g/hspa fixed the problem - likely because it was now operating at different frequencies.
Tmobile's 2g operates at 1900 mhz.
Here in chicago att's 3g network operates on band 5 (850 mhz) and band 2 (1900 mhz).
I believe when it was switching to att 3g band 2 is when the tmo service would cut out.
Verizon's cdma operates at 850 and 1900 mhz and lte bands 2,4,13 (1900, 1700/2100/700 mhz). Att's gsm operated also at 850 and 1900 mhz. This limitation might exist then to prevent 2 different sim services from operating on the same band at the same time.

Lost LTE after flashing 64 bit rom - I have LTE on Mint Sim, but not Ting! Weird

I use Ting, and LTE is available in my area (wife's on same plan) I lost my LTE/4g after flashing Cosmic OS. I've been struggling along with 3g just fine. The phone never showed CDMA - always showed "Global" in the network settings, if I Switch to LTE preferred I lose my signal and have to reset my network settings.
I ordered the MintSIM test kit, and installed it today...and I had LTE. Mint runs off of T-Mobile, Ting runs off of Sprint.
My LTE isn't gone... it's just gone from the CDMA side of things.
Has anyone else flashed Oreo onto a Sprint networked phone and retained their LTE? Is it something with the current ROMS and Sprint?
Experiencing the same after flashing FrankenRom.
Don't get LTE with Tello but I get LTE fine with redpocket T-Mobile.
