Thanks for a great app. Perfect for people who call a lot of strangers numbers for work and don't want them calling you back. It has an option to unblock contacts on the fly as well.

Prefixer is working fine for outgoing calls on my Samsung S7. Can't get it to work on incoming calls. + precedes each number. Anyone have a fix?

Very useful for managing outgoing calls from multiple phone numbers (personal, work1, work2...) based on contact group membership.

Wont fix the + on incoming calls. Tried everything and all the stuff G+ community i even downloaded barcode scanner and used it.

Does fix the dredded + in front of all in/out calls. However, Galaxy S6 was working fine on Sprint for a year. Then switched to AT&T with nano sim using Straight Talk. That's when the + started. I should not need prefixer because the root issue should not occur in the first place! Why on AT&T & not Sprint??

The app does NOT remove the + sign from incoming calls. Yes it's enabled, and yes the rule is set. Therefore, no incoming calls match my contact list, which is a pain if I'm screening calls. I had to go to my phone settings to get it to remove the + sign from outgoing calls by disabling the automatic international call function and setting that to manual.

Took about 15-20min to set up and get to work right lol Now it works great on my Verizon galaxy s7 edge running on Cricket. Dont forget to ignore this app in your task killer and startup app killer if you use them. Rule #1 only works in the free version Rule#2+ works in the paid version. Im using the free version : ) Thank you Very mutch to the creators of this app

The app doesn't work at all, on Samsung note 4, I tried many ways, but the damn plus sign still shows up on incoming calls, the ring tone I set up for each contact doesn't work well because of it, I tried every prefix I can think of without breaking other things, from xda developers, +.* being the latest, the default .*, and another, +[0-9]+, all failed. I'm guessing that this app doesn't support voice over lte setting, and maybe WiFi calling. Could be the rom I'm using but to the best of my knowledge, there isn't a complaint in the forums with this problem.

It used to work for me on previou s android phones but now that I have upgraded to xiaomi mi5 which is using MIUI 7 os on marshmallow, it has stopped working for me. I can see the pop-up confirmation anymore and call doesn't go through.

I've done everything I can do and it's not working! I paid money for this app and it's BS that we have to code it anyway. What happened to the old way when we didn't have to do anything, it just did it automatically! This use to be a good app but it's not anymore. I still have the + sign in front of my numbers on outgoing calls

I don't understand how to use this app. I downloaded it cause I have a unlocked Verizon note 4 with a at&t sim. And all my incoming calls all have +in front of them even the local numbers . And it makes it hard to call people back. There is no instructions. I don't understand how to fix my problem and those rules things are confusing. Can anyone explain how to fix my problem

It is a complicated app to use, but I know of no other that can remove the + sign on a Verizon unlocked phone. Unfortunately, it only seems to work on outgoing # not incoming. The community states that many have the same issue. I will change my review to 5 stars if/when they make it work for incoming calls as they claim.

This works perfectly. But stops after a few days. The only fix is to remove the app and reinstall.

Save me days! My phone some how receive s phone calls by 0xxxxxxxx format and sms by +nnxxxxxxxx format. And even worst, when I message from phone log, the message app separate into 2 conversations: one for 0xxxxxxx and the other for +nnxxxxxxxx. Thanks to this app, now every coming phone call will be reformat with +nnxxxxxx. And that is, it save my days!

It used to work great. Now it only works once in awhile. lt had cleared up my problem with the + sign in front of numbers. A few things I would change are to make the templates simpler and more user friendly. It takes several attempts to understand the code. Also the font in the template definitions is too small.
