Increase call quality!
 

I found this over at XDA. It really does work to increase call quality! If you need to get your MSL # just call sprint and tell them that you need to change from EVRC to EVRC-b. They will give you the MSL, no problem.

1. Go to Phone and Dial ##8626337#
2. Choose Edit Mode
3. Enter MSL
4. Change Home Orig., and Roam Orig. to EVRC-B
5. Hit Menu and Commit Changes

This is definitely not a placebo effect. Try it and see for yourself!

Re: Increase call quality!
 

Have you noticed any network issues and or change in battery life with this change?

-CC

EDIT: As always, I either ask the rep at the store for my MSL. but this time it was too busy on launch day. I just call *2 and asked for it, never a problem.

Quality is certainly different (I think I even got static noise, but it was easier to hear), also I think it actually used a bit more battery, almost impossible to tell, as the phone is new, apps change and phone usage is never the same from one day to the other.

Wondering though if all of sprint's towers are updated and compatible with EVRC-b. I am especially concerned about roaming on other provider's towers that aren't up to date or compatible with EVRC-b, I think that is why it's default to a even lesser codec.

Re: Increase call quality!
 

No network issues...To early to tell on the battery!

Re: Increase call quality!
 

Wow, made quite a difference for me. Especially roaming! I wonder if anyone has a run down of what all the different modes are (evrc, evrc-b, voice13k, etc).

Re: Increase call quality!
 

Last I heard this does not work while using the Airave. However, from what I understand this seems to work other than this. Might have to test drive it to see.

For those interested in what EVRC-B is:

Re: Increase call quality!
 

Any way to get the msl without calling?

Re: Increase call quality!
 

No way at all as of right now. Just tell the agent that you would like to speak to Evo tech support and that the Sprint store advised you to call to get your MSL to change the bandwith to EVRC-b due to poor call quality. I got mine in less than 5 minutes.

Re: Increase call quality!
 

Works for some and not for others... Worth a go...

Didn't work for me... :(

Try at the top of this forum theres a tips thread that tell you how to get it without calling sprint.

Re: Increase call quality!
 

If it doesn't work, call back and try again. Someone will give it to you!

Re: Increase call quality!
 

So this increases the volume of the call? Or clarity, or both? lol

Re: Increase call quality!
 

If you have an extra Sprint phone available you can do an online ESN swap back and forth to get it.

Re: Increase call quality!
 

Nice info gonna test it myself and from what I understand it wont affect anything else. Adding this to the tips and tricks sticky.

Called Sprint told them I was having data problems I didn't have another phone and my buddy worked for Sprint was going to help me in the morning but he told me to call and get my msl...lol
I changed the values but how do you get it to save? After I change them I go out then back in and they are back to the same old values.

Re: Increase call quality!

Re: Increase call quality!
 

The easiest way in my opinion is to use CDMA workshop (I won't tell you where to get it but its out there), open CDMA workshop with your phone connected to you CPU and dial ##3424# in the dialer. Find out what com port your phone is on in the device manager and select that from the drop down box in CDMA workshop and click connect. Then go to the security tab and under SPC click read and there you go your MSL is in the box, I can confirm this works on the old 2.7 version of CDMA workshop.

I'll give you a bigger hint. Click the tips and tricks sticky and its posted right there. :P

As suggested by other poster, you can also get your msl by using the phone swap feature on sprint.com. Even if you don't have a phone on hand or esn #, there are handy sites on the web where you may find one just laying around ;-).

Re: Increase call quality!
 

You need your MSL, not your MSID.

Re: Increase call quality!
 

I jsut did that..hope it works. Calling Sprint actually works..got the MSL code in less than 3 mins.

Re: Increase call quality!
 

Can't be on the phone with Sprint customer service at work...and alogcat does not work to get the MSL...I tried without root and with root...neither works.

Re: Increase call quality!
 

Do MSL codes carry over from your previous phone along with your phone #? I have the MSL from the device I had just prior.

Re: Increase call quality!
 

No. Different MSL for each one. I guess you may have a 1 in 999,999 chance that you could get the same one though. ;)

Re: Increase call quality!
 

Hmm, I am using a really old version. v2.1.1 and when I press read, it says "Failed...Phone does not answer" :pale: Do you have the phone connected using HTC Sync as the connection type?

Re: Increase call quality!
 

You use something different to sync. This method worked for me:

Re: Increase call quality!
 

after reading about this i went down the block 2 the sprint store and asked the tech for my msl, he looked it up in less than 2 minutes, suggestion 4 those having problems getting it.

Re: Increase call quality!
 

+1 except I simply called Sprint (Support) and requested my MSL #
and I was given my MSL# within 2 minutes. .

You may want to simply just call Sprint, worked for me :mrgreen:

Re: Increase call quality!
 

Yea I was using the newest version of htc sync and cdma workshop 2.7 (google it and its available all over the place).

Re: Increase call quality!
 

I called Sprint (*2) and they told me they couldn't give that number to me per their policy.

Re: Increase call quality!
 

Just call them back and you will get a different rep on the phone!

Re: Increase call quality!
 

Well...I finally had a chance to make that call on my lunch break. I said EXACTLY what you said here, and the woman on the phone was very friendly...she said "oh, you're one of the lucky ones who got one of these phones"...and then she said "your MSL code is ######"...very painless, and one of the better customer service calls I've ever had.

Re: Increase call quality!
 

Ah, finally got it. The key is that you have to be transferred to tech support. The general customer support folks don't have a clue what you're talking about.

Re: Increase call quality!
 

I was able to get my MSL code by asking CS to help reprogram the phone since I was having issue when pressing 1 for voicemail, another # shows up.

This thread should be change to how to get MSL code lol.

Re: Increase call quality!
 

*2, followed menus for help with phone, blah, blah, operator...

A friendly gentleman named Abraham gave me my MSL and mentioned that someone else had already called about this. He even gave me the ##8626337# code but was sure to mention that this isn't supported by Sprint.

Can't wait to try it out.
