Roam Control will work with most custom ROMs, but is not guaranteed to work with all of them.  If you find one that Roam Control is not compatible with, contact support to see if support can be added in a future release.

When the phone is in "automatic" mode, it will eventually go back to a home signal if it's available.  That is the normal behavior of "automatic" mode - it supports both home and roaming signals, and the phone chooses which one to use.

Refund requests made within 24 hours of purchase will be honored.  Any requests made after that will be handled on a case-by-case basis.

No, the app will only with CDMA networks and phones (Sprint, Verizon, US Cellular, etc).

Phones generally show a roaming triangle above the signal bars in the notification tray.  Some phones also show the current carrier under the "About phone" settings menu, or in a different menu.

No, unfortunately the 4G networks are not compatible with each other.

Due to roaming agreements between carriers, you should generally expect to receive 1x data speeds when roaming.  There are certain areas around the country where you might get 3g data speeds when roaming. Note that it is possible to get 3g roaming speeds if you flash a custom PRL on your phone.

It is your responsibility to read and understand your carrier's roaming policy.  Please go to your carrier's website for more information.

Please read the following Wikipedia article to learn about rooting: http://en.wikipedia.org/wiki/Rooting_(Android_OS) For instructions on how to root your phone, please do a Google search to find rooting guides. Rooting methods differ from phone to phone, and there is no universal method.

In general, yes, it will work in parts of the US (including Puerto Rico). However, Roam Control will not work with Samsung phones in the following areas: - Texas (outside of the Houston area) - Florida - Chicago and surrounding areas - Puerto Rico When Samsung phones are put into a "roam only" mode, they only roam on the 800mhz frequency band. The areas mentioned above only have 1900mhz towers, therefore Samsung phones will not get any roaming signal when in "roam only" mode. It's possible that this behavior can be fixed, however I'm still looking into it.

This is an issue with the EVO 3D radio.  This behavior occurs during normal use of the phone as well, it's just not as obvious because it's not switching between roaming modes as often, and usually not while you're looking at the screen.

Chances are you have a Samsung phone.  Samsung phones have different behavior - when in "roam only", they only roam on the 800mhz frequency band.  There are areas in the US that are 1900mhz only, which means that Samsung phones will not get a signal in those areas.

Roam Control puts the phone into a "roam only" mode and then the phone takes over from there. There isn't anything I can do about this, it appears to be more of a CDMA/network issue. A few things you can try: - Update your PRL - Update your profile - Try to disable data roaming - sometimes data can interfere with incoming calls - Call Sprint and tell them that your phone doesn't ring when roaming - perhaps they can do something on their end (re-activation, HLR reset, etc) Sometimes this issue resolves itself with time, sometimes not. If you experience this behavior and are unsatisfied, send contact support for a refund.

Please make sure your phone has a good signal, and for PayPal purchasers, make sure you are using the correct activation code (case sensitive). Try checking the license while connected to a wifi network as well.  Otherwise, please contact support.

Please read the error and follow any instructions that are given.  You may need to try exiting and restarting the app, or uninstalling and re-installing the app directly from this website.  Otherwise, please contact support.
