General Questions

Does Roam Control work with custom ROMs?

Roam Control will generally work with most custom ROMs (especially those based on stock ROMs), but is not guaranteed to work with all of them.

How do I tell if my phone is actually roaming?

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. Another option is to look at the network status menu inside Roam Control.

Is Roam Control guaranteed to work on my phone?

Unfortunately no, even if you have a supported phone. There are a lot of factors that can affect how the app works – the cell carrier, phone, root status, firmware version (stock or custom), radio version, PRL, and physical location are some of the things that will affect your experience. The only way to know for sure is to try it out, which is why Roam Control offers a 7 day refund policy.

What data speeds should I expect when roaming onto other networks?

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.

What does “rooted” mean, and how do I do it?

Please read the following Wikipedia article to learn about rooting:

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.

What is the refund policy?

Roam Control comes with a 7 day refund policy. If you are unsatisfied for any reason, a refund can be automatically processed through the support page within 7 days of purchase.

When I change the mode to “automatic”, why doesn’t it go back to a home signal?

When the phone is in “automatic” mode, it will eventually go back to a home signal when available. That is the normal behavior of “automatic” mode – it supports both home and roaming signals, and the phone chooses which one to use.

Will I be charged extra for roaming minutes or data?

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

Will Roam Control allow me to roam onto other 4G networks?

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

Will Roam Control with with GSM phones and networks?

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

Will Roam Control work everywhere in the US (including Puerto Rico)?

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 Roam Control puts Samsung phones 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.


I see an error message when using the app.

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.

I’m getting a license failure when starting the app.

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.

My incoming calls go straight to voicemail when in “roam only” mode.

Roam Control puts the phone into a “roam only” mode and then the phone takes over from there. There isn’t anything we 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, please contact support for a refund.

My phone does not get any signal when in “roam only” mode.

Chances are you have a Samsung phone. Samsung phones have different behavior – when Roam Control puts them into “roam only” mode, 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.
