Verizon phone switches from EVDO-1X Dropping Voice Calls

[Casey C]

I bought my wife the Verizon XV6900 the problem is at my house I get poor EVDO signal but I get great 1X service, is there a registry hack so I can force the phone 1X service? It Keeps dropping the voice calls. I would like to force it to 1X to make the phone useable. Right now the reception is terrible.

Any help would be appreciated

Not when you keep dropping your voice calls, edited the title and the original post to clarify the problem

Not a registry hack, but from the Registry tweaks thread via pdaphonehome:

To do this, you will need your MSL, which only Sprint (or your provider) can provide you. Open up the phone app and dial ##778# (PST). You will be asked to enter your MSL. Enter it, and you will be brought into the provisioning of your phone. From the top left, select Modem Settings. On this page, your Slot Cycle Index (SCI) is how often your phone polls the tower for incoming calls, etc. This value is 1.28 seconds multiplied by 2^value (i.e 0=1.28 secs, 1=2.56secs) with 0 fastest, 7 slowest. The default is 2, but lowering it to 1 hasn't noticeably affected my battery life, and roughly 2.5 second (SCI 1) response time is far more reasonable than roughly 5 seconds (SCI 2).

Also on this page is your preferred operation mode. The Default is Automatic, which is the best available mode (EV that will roll back to 1X when EV is unavailable). There are times when you might be in a fringe area and your mode may cycle frequently and this can seriously drain your battery. Setting this to HDR will force EV-DO only if you demand an EV-DO connection. Changing this setting to CDMA Only will force the phone to ignore an EV-DO tower and maintain only a 1xRTT connection.

Let me know if you need anymore help (Although I have Sprint)

Correct me if I'm wrong, but when you are on a voice call (as well as when you are sending/receiving a text message), you are on 1x only. EVDO is only reinitialized when the call has ended (or dropped). The preferred operation mode will prevent your phone from going EVDO when off a call (which, as mentioned, is good for your battery if you're in an area with poor/no EVDO coverage), but if you're having reception issues while on a call, the issue might be with your 1x reception.

Hopefully I'm wrong and setting your preferred operation mode to 1x will not solve your issue...

Thanks for the info Monk, I will try this =D>

You could be right, I don’t know. I was basing this off of when I was on a voice call with the EVDO icon on the phone I have 0-1 bars of service. When it switches to 1X I have 2-3 bars, and it seems to work better (but I guess it could be in my head)

After some searching I found it. Just in case anyone else wants it.

Change from 1 to 0

Save and soft reset

After resetting, go to:

Start > Settings > Phone > Services > Mode of operation

You will now have 3 choices, Hybrid (default), EVDO, and 1X. This is great for those stuck on the fringe areas of 1X and EVDO!
