No mobile network connection - Android Q&A, Help & Troubleshooting

Problem: I put the sim card of a stock HTC Rhyme to my Cyangenomod Galaxy S II. Sim functioned on the Galaxy S II. When i put the sim back to the HTC the network it used to run on don't show up any more, after a network search. So I can not connect to the network the sim provider uses.
Optional: The HTC phone works with other providers (sim cards) other than the provider it used to run on. It finds the networks and connects. The HTC sim card work, as it worked on my Galaxy S II and other phones other than this.
Workaround: Did various tries to get it back, entered *#*#4636#*#*. Even did a factory reset, which didn't fix anything, so that tells how messed it is.

Your HTC is amazing, try to put your provider's network signal into first choice(WCDMA, GSM...etc...)

Hehe, nothing works.

The easiest way - ask your operator to replace SIM card. New SIMs have different voltages... etc, maybe it will work if your HTC is ok with other sim-cards

That didn't work either.
I will ask the operator to push out a network signal to the mobile.
Yet the situation is very weird.

Can you try to use the search now option? I just tried it on my phone and it works fine. Also, check to make sure Network mode is set to GSM/WCDMA (AUTO MODE)
Additionally, go to settings manage applications. select menu button >> Filter >> Show all >> Call settings and select clear data.

Do you have access to a tmobile post paid sim, if so give it a try. I am not sure why it will not let u connect to the network, unless tmobile had you blocked somehow.

Had the same problem and this worked for me. Well, not exactly. Did the Setteings>Wireless and Network>Mobile Networks> Network Operators and pushed the "Select automatically" option instead. Post put me on the right track though. Thanks

I had this same issue. It was finally fixed with a new sim card. TMobile stated that there is a new sim card that fixes issues due to their new 3g+(4g) network. The sim would work fine on my older BB but wouldnt work on my Vibrant. They replaced the sim for free at the T-Mobile store and I have been fine since. I hope thats your same issue.

[Q] Orange Mozart after unlocking code enter does not get 2G signals

I have Orange provide HTC Mozart, updated to latest update (7390). Recently got the unlocking code from Orange, entered it, works OK.
However, I noticed that with Orange SIM it receive both 3G and 2G signals but with any other operator SIM it only receive 3G signals, NO 2G signals.
Any idea what's wrong?
are you worried because your phone gets the best signal?! probably other operators provide better 3G signal and your phone automatically chooses the 3G.. I think you can choose not to receive 3G signal in the mobile network settings..
Hi, no I tested it with 3G signal off but the phone is not catching any 2G signal except orange 2G.
is there any way entering the code again?
may i need to enter code manually for the 2G carriers?

GO into the HTC APPS into the marketplace u Will find it
yes u Will choose the carrier & if u change for an another Sim carrier then u Will have to launch This app again(Just One time for the App cofigure your network)
if u keep the same sim carrier it Will select the network forever
I found "Connection Setup" in HTC Apps and tried that, seems like it's the same you're referring to. I tried it but no luck. I think the unlock code only unlock the SIM but not the carriers.

[Q] My Atrix 4G does't connect to mobile internet

Hello,
I have an unlocked AT&T motorola atrix 4g mobilephone in Spain. If I put inside it a Vodafone SIM card I can connect to the internet (3G) without any problem after setting the APNs, but when I try it with a Euskaltel SIM card (an Spanish virtual mobile network provider that uses the Vodafones network) I can't connect to the internet (3G) even if I set the correct APNs.
The problem is not the SIM card because it works in a Nexus S after setting the APNs, and as I have said, the Atrix also connects to the internet with a Vodafone SIM card. But Euskaltel+Atrix doesn't work.
The wierd thing is that after I set the APNs, or activate the internet roaming, sometimes appears the arrows that it is connected but just for a few seconds and then dissapear, but even with the arrows if I open quickly the web browser it claims that doesn't have internet connection.
I have tried with other ROMs and the same thing happens, and also with an AOSP ROM like CM7 beta, there is no way to make it work.
Does any one have any kind of clue to solve this?
Regards and thank you

Try creating a new apn & call the first field "euskaltel" & the second one "internet", leave the rest as they are, click save & activate it. That worked for me a couple of months ago with a yoigo card.
It doesn't work, but thank you anyway

[Q] [HELP] "Your SIM card is unable to connect to the network."

I am from India, using HTC Droid Incredible 4G LTE in GSM/UMTS Mode. I tried this fake id method http://forum.xda-developers.com/show....php?t=1986346, but after I did nothing seems to change, so i did it like maybe three times. In the third time the phone stays in a mode something like the temproot mode where the screen becomes unresponsive and I only have the status bar on top, I can go to settings, but wasn't able to connect to my phone network carrier, only able to connect to WiFi. So, when that happens I tried flashing a stock rom 2.17.605.2 RUU http://forum.xda-developers.com/show....php?t=1770978 using http://forum.xda-developers.com/show....php?t=2214653 method, I am able to flash the phone, but the problem with the network connecting is not fixed, so now I am unable to use my phone for call, text, any services except Wifi connection. And when I search for any available network I could see the list, but when I click my carrier it said the SIM card is unable to register to the network. So I remove my SIM and insert in another phone, it seems my SIM card has failed to register, so I thought it may be my SIM so I took another SIM card and insert it in my phone, still I cannot connect to the network. Is there a way to solve this? What can be the cause of this?

No. And I figured that my phone's IMEI on the back of the phone and the IMEI given when *#06# is different. I don't know how it can be different.

You need to configure the APN's, you can google it "AT&T APN settings" in your galaxy go to "settings->in wireless & network look for 'more'->mobile networks->Access Point Names" there you can add a new APN.
