First of all, the other phone, what kind of a phone is it? And also, some phones do have better reception than others, and many other factors play a role when it comes to signal. When a phone switches carrier it only means that the signal it is supposed to attach itself to, isn't strong enough, therefore, it tries to attack itself to another signal.
Also, I give you an example. I have a 9700, and I have a "back up" dumb phone also, a Nokia 6610. Well, the other day, while waiting for the new batteries to come in the mail (had a situation where I had to give my brother my battery since his was not working) I had to use the Nokia for a couple of days. Went to a friends house, where with my 9700 I have the same issue you have. Its an area where T-Mobile (my network provider) doesn't pick up a lot of signal, but AT&T does. My 9700 in this area has barely 2 bars every time I go to his house, and it has been about almost two years now, and what happens is that it latches onto the AT&T network many times. Well guess what, the Nokia, same house, same area... FULL BARS! I was stunned and can't explain why really...
So you see, just because one phone works one way, it doesn't mean another one has to, and also, just because your 9900 does this, it doesn't mean ALL 9900 do, nor that it has anything to do with battery pulls, etc.
10-21-11 06:01 AM - To be honest we are actually agreeing here. The problem is the phone. I'm certainly not saying that it's anything to do with battery pulls.First of all, the other phone, what kind of a phone is it?

I've switched to 2g today and it's been ok so far but even on 2g it does it from time to time. I think that my only Options are to stick with the phone and it's issue or get a phone without this problem.
My issue isn't signal strength though, it's the fact that it roams to other networks even though I've got a decent signal on my network. I'm very happy with the 3-4 bars I get and the only thing I can think of is that because 3G is poor where I am, it keeps trying to get a 3g signal and therefore locks onto a network where it can get one (I.e. 3 or O2).
Why can't it just be like other phones so you can at least choose for it to only use one network and for the phone to just show no signal if there isn't one (which would never be the case at home as my signal is good).
Oh and my other phone is just a cheapo Nokia.10-21-11 09:48 AM - That's what I was thinking too. The cheapo Nokia, like mine, looks only for 2G probably, and stays locked to that carrier. The 9900 looks for 3G and maybe your carrier has weak 3G signal where you are. Not saying it is like this, but so far, it is the only thing I can think of myself.10-21-11 04:35 PM
- I've had a similar problem with my 9900 on 7.1.0 Bundle 998 and never had the problem prior to upgrading to OS7. I have a few more twists to my story though. My phone can spontaneously go to "Searching" or "No Service" during the day but that's fairly rare. 90% of the time I get stuck at "Searching for Network" when I disconnect it from the charging cord in the morning and the only solution is a battery pull. Even once it comes up and finds the network (T-Mobile) it spends the rest of the day cycling between the following: 4G, GPRS, GSM, 4g, GSM, EDGE, edge. I always have at least 3 bars and usually 5 bars because I sit at the base of a mountain with line-of-sight to all the towers at the top. For the past 2+ years we've had a Bold 9700 that sits rock solid at 3G and never loses signal at home.
My network has always been set to automatic, but I did change it to "manual" just now based on the prior post here and I'll see if that makes a difference. Also, when I upgraded to OS7 it defaulted to "WiFi Network Preferred" as my preferred network for calls. I didn't like the quality so I switched it to "Mobile Network Preferred" and that's really when I noticed all the problems. Perhaps WiFi was masking it all along.
I really think something is screwed up with OS7 and not my phone's radio antenna. BlackBerry needs to look in to it. It's the most unstable Berry I've owned.
Update: I just plugged my phone back in to the wall-charger (while it had a good 4G connection at 5 bars) and it instantly displayed an error stating "The manually selected network is out of range" and then asked me to "Switch to Automatic" or "Select another network".
I also got it to do the same thing by powering it down after connecting it to the charger and then powering it back on and disconnecting it (to simulate what happens each night/morning).
I told it to "Select another network" but after a couple of minutes it told me: "Scan for networks timed out. Please try again later." Also, while connected to the wall charger I was not allowed to scan for available networks.
I can recreate the same behavior if I connect it to my computer and select "Charge Only". As soon as it enters the "Charge Only" mode the OS is turning off the radio and only a battery pull turns it back on. No amount of changing the network from manual to automatic and back again, no amount of clicking the "Mobile Network" box on and off, no amount of telling it my WiFi network is preferred, no amount of power downs/ups does anything. HELP!!! THIS SUCKS!!!
There you go RIM engineers, I did your job for you! If any of you are monitoring this issue and would like to get additional details please let me know.Last edited by tp096255; 04-19-12 at 12:46 PM.
