[Q] Connection to provider lost until reboot

Hi there,
today i experienced an annoying issue for the 2nd time.
In normal standy use, my phone seems to lose the connection to my provider (if thats wrong, i mean the institution i bought my contract/sim card from).
It really wont reconnect, even if im going to flight mode and back. Only rebooting helps me with this...
It's showing the forbidden-sign in the top left corner, asks me whether i want to find phone networks. I do search for them and i find mine, but clicking it wont help me neither. It shows that the phone cant connect to the network.
For now, only rebooting helped, and it immediately recognized my standard network.
I don't think that it has something to do with signal quality - i am in Frankfurt central at the moment and generally connections of providers seem to be very good in signal quality right here.
regards.

It may be a sim-card problem...try other sims (if available) and if the problem seems to disappear, ask your network provider to change your sim. Usually, on contract, changing the sim card should be free.

N1 randomly loses cellulur network and often requires reboot to get it back

My N1 randomly loses the cellular network and I see the triangle with the exclamation mark in the notification area.
I am not sure it's relevant but my N1 (a refurb from HTC) does have a dodgy SIM card slot since I need to stuff a piece of paper on top of the SIM card in order for it to be registered. Still once that's done and the back is on, there is no problem.
Anyway I will look down at the phone and see that I have lost the network. If I go to Mobile Networks/Network Operators I get an error "Error Registering on Network" or words to that effect.
The only solution is for me to either switch to Flight Mode, switch back to online mode and redo the search. The various networks usually then appear and I can choose my home carrier. A reboot of the phone also works.
This suggests to me that it has nothing to do with the SIM slot and it must be some other issues. I am running an unrooted phone on 2.3.4.
Any ideas appreciated.
Thanks

I'm not sure but I think it is probably related I would call htc and see if they can take a look at it cause for one they should not have given you a phone with a faulty sim card slot and it probably brought along some other problems.

[Q] Htc One not able to connect to the Network

I have been using my Htc one from the past 2 years using the same sim card. Since i stay in India, the phone goes into roaming mode when you travel across states. So 10 days ago, i travelled to another state and my phone entered into roaming mode from then my phone cannot be connected to the network. I am unable to use the cellular services. Sometimes my phone works fine but the next minute, i loose the signal again. It is not in a stable mode, it keeps loosing and gaining the connection. Neither can i call nor i can text. If the phone gains signal, it happens only for a minute or two after that, it looses the network again.
My sim card is fine since i checked it in other phones. So the problem is with the phone or the sim tray.
What should i do?

Seems strange it happened after / during traveling
I have herd of others putting a piece of tape on the back of the sim to make it a little thicker. be careful doing this though the sim could get stuck in the phone permanently

No signal/voice/data - Restricted access changed. Voice service is blocked

Just as the title says, the phone was working fine then suddenly it lost all signal and went into some kind of restricted mode, it's a friend's phone and he is almost 84 years old.
I have flashed the latest firmware and factory reset to no avail, also changed sim cards and here comes the weird behavior:
I don't have a standard-sized sim card so I had to take it from my USB LTE Modem, it's from another carrier and the phone detected the sim card, went with a full -77db HSDPA signal but data doesn't work at all, it seems to be disabled on status, even configuring the proper APNs it refuses to work. Can't test voice and all my other working sim cards are nano.
Inserting any other sim from another carrier results in no signal/restricted access but the phone still downloads the Internet/MMS configuration.
Have tried setting it manually to WCDMA and GSM, nothing seems to work, only my data sim worked so far *without the data*.

Maybe the IMEI is banned for some reason?
Never heard of this issue until now
Have you tried to flash a firmware that aren't from any carrier?

Yes I did, flashed the USA unbranded kitkat rom.
Just got the chance to test with two sim cards from different carriers:
Carrier #1: Registered on network, no data traffic, voice call drops just after trying to call, signal ok
Carrier #2: Registered on network, data traffic seems ok but can't navigate, shows H+ and proper APN and traffic arrows activity but when you try a call it says "Mobile Network Not Available"
Can't send SMS, they stick with a "Sending" status and wont get past it.
This phone was purchased unlocked without a contract, can't see how the IMEI could be banned, plus we do not have regularization for IMEI ban in my country, it's currently a mess.
On a side note it does not detect the sim's phone number which it does on any other phone.
Maybe it's some hardware related issue?

Well that's interesting
My phone can't detect my Sim's phone number either (though i don't know If it is only for me)
Have you tried to flash a ROM? (from XDA)

The sim number information depends on the sim itself, most carriers register this information within the simcard so when you go to status you may retrieve your own phone number but I have seen sim cards without this info. The sim cards I tested do have this information and were available on a Galaxy S5 and Xperia Z1 but this E1 fails to read this information which kinda indicates a problem. I don't remember the codes for debugging the sim and network info or I'd give that a shoot.
I will try a custom rom, maybe a different kernel and see if the behavior changes any bit.
I am bidding on a Z1 Compact for this friend, should be a proper replacement and a hell of an upgrade, just concerned about E1's loudness which is certainly superior.

Interesting, I also get this if I don't reboot my phone after like 5 days.

Freedompop won't show network connection in notification bar.

So I'm using this phone with Freedompop's global SIM card as a handy data connection device. I've been using this sim with other phones without a problem, however I have a strange behavior on the Blu R1. Apparently, since the card is always considered "roaming" here in the US, the R1 just shows me a "R" next to my signal bars. However, I am unable to see if I have a network connection, or at what level (3G, H+, etc). I set the network preferences to always connect when roaming, but I hate being in the dark with my connection.
I can pull up a browser and see if it works or not, or open up the Network app or something to see the nitty-gritty status, but its very frustrating to not know how or even IF I'm connected when I'm expecting a message or response. For example, if I'm on H+ I'll accept a video call, but if I'm on 3G I know it'll just end in frustration. Is there any fix/tweak or anything to get around this? Perhaps disable the roaming notification?

I'm not having quite the same problem with FreedomPop. I see the perpetual R for roaming, but I do get bars for network signal strength. (You do have the FreedomPop Sim in slot #1, right? It won't work in Slot #2.)

FreedomPop will ALWAYS show as roaming here in the US. It is part of their instructions actually. But you will not be charged extra for it. I have had the free 200mb, 500 text, 200 minute plan on my sons R1 HD for a few months now and no bills.

If you have Xposed installed, you could use the Roaming Control module to trick your phone into thinking that AT&T and T-mobile aren't roaming networks; it's what I did until I switched to the FreedomPop LTE GSM sims.
Otherwise, I used to use Network Cell Info Lite, where I enabled the notification and set the update rate to 4 seconds--HSPA+ will show up as "3.5G" in the notification icon. It has proper support for dual-sim phones. You could also try Nify, which does show what kind of network connection you're on, but I have no idea if it works with dual-sim phones properly (e.g. will it only show SIM1 all the time, even if you use SIM2 as your primary sim?)
