Roaming Tips:

TIP #1: LEARN HOW TO USE YOUR PHONE WHEN "ROAMING"
You're on vacation and want to check your voice mail, but it won't work. If you are roaming outside your network's service area you may need to call your own number, instead. Codes like "*VM" may not work while roaming. If you're out of the country, a certain dialing sequence is required. GSM phones may decipher the sequence for you by adding a "+" before the number, but most likely, your phone book entries won't work without adding the proper prefix. Check your carrier's web site or customer service for instructions on what to do if you might travel off their network.

TIP #2: MAKE YOUR PHONE ROAM (or NOT Roam) TO ACCESS A STRONGER SIGNAL
There are different menu selections in some phones that will help you change which network the phone accesses. Some of these selections are called "Mode" or "Network", and they can be switched to "Cell Only", "PCS Only," "Roam Only", or similar, which may give you a different network. There is also a "NAM" or "Line" choice that will allow you to program a different "Home" network into the second, or main, "NAM" (Number Address Module). You would change the System ID (SID) for your own network to the roaming network. We have a page with a List of SID's. Hints on how to perform these changes can be found by conducting an internet search.


TIP #3:
CAN'T GET THE PLAN OR CARRIER YOU WANT IN YOUR AREA? SIGN UP WITH A DIFFERENT ADDRESS, OR AT WORK
Some carriers forbid this, but most don't care. Sign up with an address of a friend or relative in the area you'd like. Most carriers will allow you to go "paperless" and pay online or on the phone, and you won't have a bill going to the friend's address. You can also sign up with your work address and get the bills there. This is very common. Your employer may have a discount deal with certain carriers. Be aware that you might not get a phone number local to your 'real' home. If that's important, you can get an '800' number. Expect to explain if most of your calls are roaming and off the carrier's network. You could even get bumped off as a customer.


TIP #4: DID YOUR PHONE START ROAMING ON A WEAKER SIGNAL?
You can change the PRL or MNC. Some carriers may do it for you, or you might be able to either download a different Roaming Code, or edit your own. If you are familiar with your phone's setup menu you can try selecting "Home Only" or some of the suggestions in TIP#2, above.

ABOUT THE ROAMING ZONE:
This site was split from the Mountain Wireless Reviews web site and since has been refined and updated. We travel across many parts of the country using cellular service, and we have added contributions from dozens of other like-minded cellular users. This site is a result of constant monitoring of the web as well as our contributors and their observations as a volunteer effort. However, there are costs in running this site, and those expenses are paid by a small commission from "affiliate" and sponsor links. So, if you ever buy cellular phones, service or accessories online, we would really appreciate you doing so by clicking on any of the advertising banners and links you see on our site, like the ones above, or shop at any of the links on The Roaming Zone Online Discount Page.

We welcome updates about new or incorrect information and we will correct any errors as soon as possible. We make no warranties to the information, which can change at any time without our notice. But accuracy is the desired goal. And, as with all small operations, there is a lot of information that gets put on hold until time is found to update it.

The picture at the top of our web pages is looking southwest along US Route 163 into Monument Valley. Most of what you see is located in Utah with the Arizona state line running east to west (left to right) behind the first row of mountains. There is a Commnet cell site just to the right of the picture (near Goulding's) serving CDMA and GSM roamers.

What's with the ? It's the international symbol for cellular roaming, but we don't see it as often these days as cellular carriers now own larger networks or include free roaming across much of the US.
