Sprint ERI on verizon Roaming Fix (updated PRL's)

[tomz17]

Works on my sprint 6900 converted to verizon... editing the ERI would be much more elegant. But since nobody seems to know how to do that (YET), I updated the PRL!


For the 6900, just put the correct file on your memory card and dial ##prl# or ##prl send


-----------------------------------------------



If you have a sprint phone converted to verizon, and can't access/update the ERI (common problem) resulting in a constant roaming indicator/icon, here are some modified PRL's to help you.


DISCLAIMER, USE THE BELOW INFORMATION AND FILES AT YOUR OWN RISK. IF USED IMPROPERLY, OR IF THE FILES CONTAIN ERRORS YOU WILL NEED TO MORTGATE YOUR HOUSE TO PAY FOR RESULTING ROAMING CHARGES. I TRIED MY BEST BUT I AM HUMAN AND MAY NOT HAVE CHANGED EVERYTHING CORRECTLY.

The 51099 PRL (AC1) PRL is from my own phone, and the 51101 (AC2) PRL is from a sticky here.

The Verizon ERI values are (in decimal)
64 Verizon Wireless (indicator off)
65 Verizon Wireless (indicator solid)
66 Extended Network (indicator off)
67 Extended Network (indicator solid)
68 Roaming (indicator solid)
69 Extended Network (indicator flash)

The Sprint ERI values are (in decimal)
0 Digital Roam (sprint default)
1 Sprint PCS (no roam)
2 Digital Roaming (my default)
3 Out of Neighborhood
4 Out of Building
5 Roam Pref Sys
6 Roam Avail Sys
7 Roam Allince Prtnr
8 Roam Prem Prtnr
(there are more, but i got bored of resetting my phone)


Verizon doesn't seem to use 65 or 67 anywhere in it's PRL's.

So the methodology I used was to convert the roaming indicator value to the correct corresponding number in the Sprint ERI. (e.g.
64 -> 1
66 -> 1
68 -> 2
69 -> 5


In other words Roaming indicator off will give you a SPRINT PCS banner (with no roaming indicator). This means that you are safe to place calls on AC1 and AC2 at your normal rate plan.

Verizon Extended Blinking will give you a ROAM PREF SYS (with roaming indicator). This means that your rate plan still applies, but IN-calling does not! (so roam indicator is activated to alert you if your phone supports it)

Verizon ROAM Solid will give you a Digital Roaming banner (and roaming indicator). This means that you are paying extra for all phone services on AC1 and AC2 (roam indicator active to alert you).


HOW to use
The zip file includes
51099.prl (original 51099 AC1 PRL)
51101.prl (original 51101 AC2 PRL)
51099m.prl (modified 51099 AC1 PRL)
51101m.prl (modified 51101 AC2 PRL)

text files are included for each PRL so that you can see the changes yourself

If you have AC1 (America's Choice 1) load 51099m.prl onto your phone
If you have AC2 (America's Choice 2) load 51101m.prl onto your phone

Instructions for doing this vary by phone (if you have converted a sprint phone to verizon, then chances are you already know how to do this)

P.P.S. I did this by hand in QPST... If you want to write some software to do it here are the specs for the 683-C standard for the PRL files.
