Ok so I have a 1.1.2 OTB phone, and I purchased a StealthSim to unlock it. I cut my sim, and put both my sim and stealth sim into the tray. It works fine, but at random times during the day I get a no service message for a while and then my carrier refreshes and my carrier is displayed again (FIDO carrier in Canada). I heard that on the 1.1.2 models, the phone refreshes the SIM every time your phone connects from tower to tower so I think this is what's causing the problem... Someone told me to update the lockdownd file, but I don't know what that is or how I can do that. This gets really annoying sometimes because if I'm talking on the phone it'll cut out sometimes. Please help me guys! Thanks in advance.

P.S. I live in Canada, and my carrier is FIDO. Someone said install iWorld, but I don't think that's ganna make a difference.

Aren't you the one always preaching about using SEARCH?

Time to practice what you preach!

I have searched dude. That's where I found out that maybe installing iWorld or updating the lockdownd file will help.

Don't accuse me of not searching. I've searched for a while now, and still nothing.

Doesn't feel good, right? Remember that next time you try to flame a newbie that can't find something because he's....a....new

Now, for your problem. If you're not getting a "no sim" then you have nothing to worry about. I have seen "no service" several on my phone and others I work with, and it's because we were in a part of the building that masks cell tower reception. This also happens in my home in certain areas sometimes. The phone service will drop out when the signal is below a certain dB. I have noticed that my iPhone seems more sensitive to signal loss than other phones.

In short....when the phone gets to a certain dB it gives up and displays the "no service" message, then when you pick it up, your body amplifies the input and "voila", you get reception. Modern technology, no matter how awesome it seems, still misbehaves sometimes.

Leather cases or metal cases will definitely screw it up too.

There is much more about this on google.....check it out....interesting stuff.

Thanx bro, I appreciate it. I just find it annoying sometimes because when I'm in a call and I'm traveling (driving) the conversation will cut off due to the no service message. Is there NO way possible to correct this? What do you do to avoid this or at least try to minimize it. Can you give me some tips? Thanks in advance, and it's much appreciated.

Do you live close to the city? Or do you live on the outskirts? I'm originally from New England which is similar to Canada and I used to lose signal with every other turn of the road.

If you have service, then your sim and phone are working perfectly. You are able to buy antenna boosters for every phone except the iPhone. I suspect that at some point we will need to replace the antenna or install a booster.

When I sit in my living room I get two bars. When I move to the bedroom I get 5 bars. I live in Tucson and homes are constructed here with wire and plaster, essentially creating a cage around me, which scatters the signals....it's hell on my wireless routers.

The housing of the phone itself can cause an issue. The metal band for example can cause issues as well at the metal apple logo that sits atop you cell antenna.

As far as checking the sim every time you switch towers.....that isn't true. You are logged into 3 towers at any one time....you will be in the cell system as a subscriber and as you switch to the next tower your carrier signal is transferred.

Here is one thing that will help you tremendously. Turn off your wifi until you have a need to use it. Your wifi antenna is right next to cell and bluetooth antenna. While driving around leave it disabled and stick with the edge. After I adopted this practice I never saw this problem again....guess I should've started here, huh?

Haha yea.. Thnx dude. I'll defenitly try this. I live right in the heart of the city (Downtown Toronto) so the reception around me is pretty solid. But thanks a lot dude, I really appreciate your help.

By the way, sometimes I have gotten the NO Sim problem. Is this because it's not aligned properly?

You got it. Let me know if it returns. Like I said, once I started this method it went away.

When I leave the house I get 5 bars, it's just in the house that things get wacky.

Maybe we can talk some of these programmers into writing something that will alleviate this issue.

No Sim is definitely an alignment problem. Use a small piece of "Scotch" tape on the very top of the cards to hold them together. As you push them in together they will shift a little, and the stealth will sometimes shift as you move the phone. The tape will firm them up.

Give it a try.
