Coming from Samsung Captivate...

What do I need to know moving from a 3G phone to a 4G phone (HTC Inspire)? Will the SIM and everything work with the phone right out of the box? Will I be charged extra for being on 4G?

Switching sim cards is not an issue. 4G technically doesn't exist yet for the Inspire.

I need to switch out my SIM card or it will work as I have it?

It will work just fine.

It should work just by swapping sim cards. Eventually you may have to get a new sim when HSPA+ rolls out.

Sounds great...thanks guys.

There should be some clarification made here. The Inspire requires a 4G data plan code to be added to your account - and it does require a new SIM if you are in a 4G area. Most of the coastlines around the country are 4G already. Well... "4G" anyway - the maximum theoretical modem speed in the Inspire is 14.4Mbps/5.76Mbps, which is pathetic considering T-Mo's 21Mbps phones and their 40+Mbps network.
Verizon currently holds the speed crown overall in the country when it comes to 4G speeds but it really depends on your area. Here in Colorado, Sprint bested both Verizon and T-Mobile on "4G" speed (WiMAX in their case) by a good margin in random tests by an independent lab not hired by Sprint.
Either way, I've seen T-Mobile tests that have passed 25Mbps - no joke - and I've yet to see more than 10Mbps (this was a test on Sprint) or 7Mbps on Verizon but at&t struggles to get 2Mbps so its a huge upgrade anyway.

According to several ATT corporate folks the 4G sim cards will probably not be required for some time. Its basically a new paint job on the old cards. And this is coming from the Dallas/Fort Worth area, aka Big Blues Backyard. Eventually 4G will he turned on. Then ATTs version of LTE. And it will be widely used & consumed. But until then its no real worry. Think about when 3G phones first started rolling out. We were still rocking our old sim cards for quite a while but there was an eventual need to change.

I got the information straight from a manager in business services. The new SIM cards that are being deployed with these phones are required, along with a new SOC code for "4G" internet service to work when it is deployed. If you go to at&t's website and look at their 4G map, it has been turned on in a very small number of places (Texas and Buffalo, NY to name two) and if you are using an old SIM, you will not get the faster speeds. I hate this SIM card business honestly. Coming from CDMA, it royally sucks when you have an issue and your cell is your only phone because of the fact that inactive SIMs cannot call 611. I went through that hell today. Inactive CDMA phones will still call customer service, giving you the freedom to get technical support without much of a fuss. I had to call at&t three times today because of provisioning issues with my Inspire and being unable to call from another phone.
In any case, if you are in a 4G area, you need a 4G SIM to be able to connect to the HSPA+ network, just like EDGE SIMs didn't connect to the 3G network when it FINALLY started to launch.

Well when I bought mine they changed the sim I used to have in the iPhone 3G with a new one... So I guess you should to.. It's free so why not?
It's true the 4G it's more an 3 1/2 G but what is gonna happen when they actually enable it???

This is why I said you "may" need the card. At&T has been vague on this

In a 4G area, but stuck on 2G. Phone is useless. Any ideas?

I've already rebooted, removed battery/sim, tried to switch network modes, etc. I can't get it to connect to 4g and I'm in a "4g very good" area. I contacted tmobile chat and they are not sure what is happening and suggest I swap for a different phone. Really? Is this a common problem?

Maybe you can check out one of the many threads concerning data issues instead of making a new one.

Where do I find this information?

Assuming you purchased the Sensation from T-Mobile it shoudl work as long as they placed a 4G capable SIM in your phone. Without it you won't be able to receive 4G service.

Is there a way to tell if I received a 4G capable sim? I ordered online, so I just got it in the mail today.

I went in today and Tmobile swapped out my sim card for a new one - I get the same issue to. And I was advsd they are not 4g cards - just updated cards

The guy on chat said there are currently no 4G outages in my area.

Where they able to replicate your issue on any of the handsets at the TMobile store? If its a coverage issue all of the phones at the store should experience the same problem. Unless it's something specifically wrong with your phone.

You tried switching the network to CDMA only? That should not let your phone connect to 2g
Sent from my HTC Sensation 4G using XDA App

Well guys, I went down to a t-mobile store and guess what?
4g isn't up yet in my area. They are currently working on it.
So that's kinda messed up...I mean, the coverage chart shows 4g up and running in my area already. I drove to the city next to mine (10 miles), and sure enough, 4G pops up.

the coverage map in green is not for 3G or 4G. its for the 2G network. try locking it on WCDMA ONLY if you don't get a signal you are outside of the 4G coverage area. I just use WiFi. what city is this?

I know the coverage map in green is voice, the purple/pink map is for 4g. That map shows my area covered under "4g very good."

Correct me if I'm wrong but doesn't it go to 3G if you don't have 4G? And if you don't have 3G it goes to 2G(EDGE)?

So basically, on a 4G phone you can't get 3G?
Let's say a 3G phone enters that area, it'll get 3G right?

From what I understand, 4g is basically 3g, so if you don't get 4g, you go to 2g.

*Compairson* One S On AT&T vs T-Mobile - Network Flopping

I thought I would bring this up.
I have the T-Mobile US One S carrier unlocked and I have used it both on ATT and Tmobile.
With all the network flopping going on I noticed something between the two. When i use the phone on ATT, I rarely see 3G. It's always H. And the speeds reflect that.
When I use the phone on T-Mobile, it's always on 3G. I only see the H when the phone needs to do something data intensive. For instance, I start a speed test.. It will start 3G and flop to H for the test. I can sit with the screen on playing around with the phone and it will not switch H at all. I am in a good 4G coverage area.
I know many users are looking for a update to fix the flopping. However, to me it seems more like a power management thing and perhaps on Tmobile's network side.
Just a thought.

I was wondering if you've been able to use AT&T's network with your T-Mobile sim? I haven't, but I thought the Roaming agreement was all set. Am I wrong?

According to the coverage maps, postpaid and prepaid are identical. However, I have seen this as well. I can have full ATT coverage and zero T-Mobile coverage.

3g on ATT with Galaxy Relay?

So, my phone is rooted and unlocked.I pop in my sim card, put in access point info that was in my old phone that got 3g (desire z/g2) and I only get edge. Am I missing a step? Did Tmobile block att bands for 3g use in the USA?

I figured it out. Network mode was set to GSM. When it was switched to GSM/WCDMA 4g came in great. Not sure why that would be, as ATT uses GSM only, but there you go for anyone that's searching. :good:

Do you mean 3G came in when you switched to GSM/WCDMA? Its my understanding this phone, despite its name, can't actually get 4G but rather a somewhat faster version of 3G when 4G is switched on (online it seems to have the unofficial title of 3.5G).

As i understand it what the phone companies call 4g is not quite actually 4g. Its 2 channels of 3g which gives a net speed in the 4g range. But 4g lte is actually a 4g connection, which the relay doesn't have.

Meaning the Relay 4G won't be able to access AT&T's 4G connection.
I'm more concerned with it being able to access AT&T's 3G connection. There isn't enough 4G LTE coverage for me to really be concerned with a phone that can't access it. In 2 years times, YEAH, but for now, no, I just want decent 3G.

It shouldn't have a problem, as long as it's unlocked and you've set up your APN properly. I've moved my T-Mobile service to an LTE-capable LG Optimus F3, and put an H2O Wireless SIM into the Relay (H2O is an MVNO that uses AT&T's network). AT&T's HSPA+ works fine on my Relay.
The labeling of HSPA+ as "4G" was pure marketing BS; T-Mobile started with that, and AT&T followed suit. I suppose that dual-carrier HSPA+ reaches into 4G territory from a speed standpoint, but I've never seen DC-HSPA+ outside of T-Mobile's network.

I've read about T-Mobile's marketing "trick" but I didn't realize AT&T did something similar.
Well like I said, once I get this phone I should be fine for a good 2 years just using 3G and data. That should give the market time to catch up in the 4G department, by which time I'll be ready to move on to another phone anyway. Thanks for the info. :good:

Yes, "H+" (aka 42Mbps 3G) works fine on the Relay with AT&T Go Phone. It's what my wife is using, and it works fine. Faster than my 21Mbps HTC One X on Go Phone.

[Q] 4G LTE/HSPA+ on Net10 with Skyrocket

Okay, so heres the deal. I currently have a Skyrocket running CM 10.1 with the UVMC6 radio on Net10 T-Mobile SIM. I my home town of West Bend, WI I get H+ and decent speeds of about 6Mbps down. When I'm in Milwaukee, WI I occasionally get "DC" (Dual Carrier?) with some pretty impressive downspeeds of 20Mbps. I have LTE enabled on my phone but I have never gotten a 4G or LTE indication when in Milwaukee. Which I believe is a T-Mobile LTE area. So my question is if I switch to AT&T SIM on Net10, will I get 4G LTE speeds? It is not specifically indicated on Net10's site that I will, but they sell LTE phones.
Thanks!

It all depends on what net 10 (or whatever) are providing...I doubt those MVNO networks offer LTE from the patent networks at this moment, though I might be mistaken...That 20 mbps you get is HSPA+(DC is HSPA+21 x 2 = HSPA+42)...They sell LTE phones doesn't mean anything, most modern phones nowadays are LTE phones....
However, if you join T-Mobile(T-Mobile proper that is ) and in an area which is one of the official LTE launch cities, you can connect to it using the stock SR radio...
To know the type of network you're connected to, go to settings/About device(or phone)/Status

Thanks! I was wondering how I could be getting speeds that fast without LTE. Also, is HSPA+ is rated for 42Mbps then how fast is LTE rated for and is the 20Mbps down that I am getting relatively high for cellular speeds these days?

It depends on tons of factors...HSPA+ at 20mbps is faster than the LTE I get....The only real plus to the LTE is the excellent low ping latency...

They have tried telling me that my phone is incapable of mms when i was having problems with the stock apn they provided. I wouldnt trust any infomation they tell you.

Those MVNO networks and their customer rep suck big time to be helpful at all....

I use my Skyrocket on Net10 AT&T SIM and the best I have ever gotten is HSPA+ 21.6 even in an LTE area... Net10 SIMs don't allow connecting to LTE networks.

If the frequencies are the same as Rogers / AT&T then there's no reason for you to not have it. Try doing more troubleshooting.

That's what I figured, I mean it's an ATT phone after-all so if should work with their LTE. But after some troubleshooting I discovered that my phone will not enable LTE for whatever reason. I will go into the settings menu and select GSM/WCDMA/LTE and it just auto switches back to GSM/WCDMA preferred. I am currently running CM 10.1.3 RC2 with UCMC1 radio, so I will try re-flashing that radio to see if it helps, but I don't know what else would cause this.

Try Rogers RUXUMA7 radio, I think that the UCMC1 radio has some kind of lock which prevents you from switching modes.

I have the exact same problem. 20 minutes on the phone with Net10 today and they said I would have to contact the manufacture(Samsung) to get LTE. Made no sense.

Go to network operator, scan and pick att from the list. Then try changing the mode to lte/gsm/wcdma and it should stick. Was happening to me too but this fixed it
