"No Service"

I just bought a fido sim card and I get the msg: "cannot register on this network. choose another network, or disconnect your data connection and try again" when i try to manually connect to the network. I have using this phone with at least two sim cards back in my outcry and i bought it independently from my previous network from an eshop in Ireland..
Any thoughts? Could be the ROM and radio installed?

maybe you just need simunlock, to get it go to http://forum.xda-developers.com/wiki/index.php?title=HTC_Blackstone#SIM_Unlocking
I have tried to unlock the sim but the text file doesnt contain any 8-digit number.. So i assumed that this is not the problem..
changing the sim does not change anything in your system settings so maybe you need to adjust some settings to get it working. go to phone settings and look at the band and network settings. once you did that your sim should be able to register with the network, then run the connection wizard to set up your 3g and mms settings.
some settings are also stored on the sim card itself (including call barring, call waiting, sms service center...). eventually you should have a look into that as well.
if it isn't in the settings, you should post more information on your device. what rom/radio rom/spl are you running?
I have already played around with the band settings but nothing. I also have run the network wizard several times, but nothing either..
My ROM is 1.59.23148 SL7.1 WWE and the radio 1.13.25.24
I flashed the official rom:RUU_BlackStone_HTC_WWE_1.56.405.1_Radio_52.62.25.34_1.13.25.24_Ship
and when I try to set the network type to GSM (from auto selection) or/and band to 850/1900 I get the msg: "Warning: Unable to change the GSM/UMTS Band, Please try again later."

G1 unlocked but no service

Hi I recently unlocked my G1 with a code, I had service. after I had to activate the phone but my sim card wasn't provisionned for data.so I turned off.Now when I put sim card the phone don't see any network,it don't ask me unlock code.I have no ideas please help me.
do you have tmobile sim? you shouldn't need a code.. but if you dont have a data plan it shouldn't matter anyway bcuz you cant do anything with the sim... basically can only use wifi and if your device is rooted you dont need a sim, sorry if i mis understood the question
Once you unlock your G1 from T-Mobile, it stay unlock. You can use any SIM from any network, but you might have to setup the APN for your vendor. (IE: AT&T, Sprint, etc...)
As stated by ldrifta if you don't have data service from your vendor, you can only get internet (online) using wifi.
So, in order for you to get provision you will have to get with your vendor to pay for the service.
I have good apn settings for my vendor mcc,mnc,apn and so but I still don't have service. I'm anxious for that, or I need to activate first using wifi before having service?
Since you have already unlock your G1, my suggestion is to get the data service. So you can start using it.
I tried a friend sim card provided with data service but it sill don't see any network,no service.Do you have any idea about it.Thanks
Go to Setting >> Wireless & Network >> Mobile Networks >> Network Operators
And select your vendor network you supposed to be on. That should registered your phone on your vendor network.
ok I will try

can't register on network with g1

I unlocked successfuly my tmobile g1 coming from usa, but now I have no signal and unable to register on network.when I go in settings,wireless control,,mobile networks.when i ask for available networks i have this error message:"error while searching for networks".even when i choose select automatically i have this:"your sim card does not allow a connection to this network".we have GSM, GPRS, and EDGE in my country.Do you have any idea?thanks!
It's your SIM card being locked to a specific network. You might have to contact your vendor.
I don't understand,my sim card locked?I don't have pin code.you are talking about my foreign sim card(non tmobile?)could you explain more?
I don't know why either. I just know that is what happens. I had the same problem with my SIM too when I went on vacation. But I didn't bother trying to fix it. Since I brought the local SIM to use because I didn't want to pay the international rates.

Unable to register phone on T-Mobile network

I've been a T-Mobile customer with my OnePlus 1, got the OnePlus 5 today and went by the local T-Mobile store and got a new SIM card. A couple hours later I got around to actually setting up my phone. I realized I wasn't getting app verification codes, so I called T-Mobile to make sure the SIM card activated properly. She had me confirm the SIM card was inserted properly, then she had me turn the phone off and she "sent it a signal." That got text and data working, but still no go on the phone. She transferred me to the next tier up tech support. On the phone with them, we turned off WiFi, WiFi calling preferred, VoLTE, and automatic selection for Network operators. The phone did it's search and we selected T-Mobile 4G for the Network operator. The phone says it registered on the network, but T-Mobile says it didn't. We tried the second SIM slot but no change. We did a couple reboots and still a no go. I was then told that since it's not a T-Mobile branded phone, they can't guarantee that it will work. They recommend I put the SIM in a T-Mobile phone to confirm that the SIM works - I'll do that when I get home and try it in my wife's phone.
When I turn on VoLTE, I get text and can make calls, otherwise if I make a call, it just calls T-Mobile.
Under Settings > About phone > Status > SIM status, Cellular network state shows disconnected.
I also see under Settings > SIM & network > SIM 1 > SIM name it shows the name as T-Mobile but Carrier says Unknown
Fresh out of the box, running 4.5.3. Has anyone else had any problems getting their OnePlus 5 to register on T-Mobile? I searched the T-Mobile support site but didn't find anything helpful.
I'll try the SIM card in the wife's T-Mobile S7 when I get home, but if anyone has any pointers, I'd appreciate the help.
OnePlus 5 on T-Mobile here and no issues at all.

Same here. I also have 0 issues
Are you using the latest 4.5.4 update for OP5? They had fixes for VoLTE not connecting. Even though I think that was Europe only thing, the download made its way to my phone automatically. If you're not on 4.5.4, go upgrade (it's a simple thing to do)
What are your APNs set to?
Goto...
Settings
Sim and network
Sim x (1 or 2, wherever the sim is installed)
Access point names
Without doing anything besides entering my sim card into the phone and starting it, I have 4 options
If you have anything outside of your current provider, add them. The easiest way to do this is to open up another TMobile phone you have, goto to the same location on that phone and copy settings manually to your OP5.
I did this for my wife's S7 coming from Verizon. Although she doesn't get WiFi calling without flashing firmware (which I'll be doing when she's ready) you shouldn't have that issue.
Bad SIM card
Turns out the SIM card was bad. Went to the T-Mobile store, let the guy double check everything, then he grabbed a new SIM card, popped it in and two minutes later everything was working. I asked him how often he sees bad SIM cards, he said one or two a year.

Mobile network state disconnected?

Hello guys. After paying off the remainder of my S8's bill on sprint they unlocked it (or so they said). I then used your guide to install Samsung and at&t's firmware. From there I went to an at&t store, bought an at&t go phone sim card, installed it, activated their service and changed my number. LTE works fine, but I don't think 2g and 3g are working.
1. Under sim card status it says disconnected mobile network state. My IMS registration status is not registered either.
2. Under connections - mobile networks - network operators at&t - search for at&t microcell it says "Failed to connect to mobile network via at&t MicroCell. Try again.
3. Under connections - mobile networks - access point names it says "ATT Nextgenphone", that's all. I would of thought more options would be here. ?
According to the app open signal my phone never uses 2g or 3g.
Please let me know what I should do next. Thank you.
