Many travelers enjoy the convenience of bringing their own mobile phone on trip abroad. Using your mobile device abroad isn't hard, and with a little preparation, you can text, make calls, and access the Internet without breaking the bank.
How to Set Up (or Disable) International Service on Your Phone
Roaming with your own phone outside the US generally comes with extra charges, whether you are making voice calls, sending texts, or accessing data (going online over a cellular network rather than Wi-Fi, aka "data roaming"). If you plan to bring your own phone, start by assessing how you will to use it — whether you will be making a few or a lot of phone calls, sending and receiving text messages, and how freely and frequently you'll want to get online, or use other mobile apps.
You can pay as you go on your normal plan for all three services. But the costs can add up (on average and depending on your phone carrier, about $1.50/ minute for voice calls, 50 cents to send text messages, 5 cents to receive them, and $20 to download one megabyte of data).
Travelers who want to stay connected at a lower cost can sign up for an international service plan through their carrier. Most offer some sort of global calling plan that cuts the per-minute cost of phone calls and a flat-fee data plan that includes a certain amount of megabytes. Your normal plan may already include international coverage. It's a fairly painless process:
Confirm that your phone will work at your travel destination. Nearly all newer phones work fine abroad (as do older phones purchased through AT&T and T-Mobile), but it's smart to check with your carrier if you're unsure.
Research your provider's international rates. Plan pricing varies wildly by carrier. Call your provider or check their website for the latest pricing.
Activate international service. A day or two before you leave, log on to your mobile phone account or call your provider to activate international roaming for voice, text, and/or data (whichever features you plan to use), and sign up for any international plans.
Cancel international service when you get home. When you return from your vacation, cancel any add-on plans that you activated for your trip.

With any laptop, tablet, or smartphone, you can get online via a Wi-Fi signal, which is usually free. If you have a mobile phone (smartphone or basic) or a cellular-enabled computer, you can get online over a cellular network, but you'll usually have to pay for it.
The most cost-efficient way to get online is to log on to Wi-Fi hotspots during your trip. Even if you have an international data plan, you're better off saving most of your online tasks for Wi-Fi.
If you plan to use any new apps on your device — such as language translators, ebook readers, or transportation or mapping apps — it's smart to download or update them before your trip, when bandwidth isn't an issue.
Most accommodations offer free Wi-Fi, but some charge a fee. In some hotels, Wi-Fi works great; in others, the signal is less reliable or doesn't work well (or at all) beyond the lobby. Often it's good enough to shoot off an email, but too slow to stream movies or make a video call.
If Wi-Fi is important to you, ask about it when you book and check that it'll be available in your room. As soon as you arrive at a hotel, ask at the desk for the password and network name (in case several are in range).
When you're out and about, your best bet for finding free Wi-Fi is often at a café. They'll usually tell you their Wi-Fi password if you buy something. As in the U.S., most McDonald's and Starbucks offer free Wi-Fi. You may need to register or accept terms of service to get online, and some networks limit browsing time.
Tips for Using Data Roaming Smartly
Using data roaming on your cellular network is handy for times when you can't find Wi-Fi. But while convenient, data roaming is also potentially expensive, depending on your international plan rates. You'll want to be conscious of how much data you're using, since you're probably paying for a limited amount of bandwidth. Still, data roaming can be worth it when you're out and about, need to get online, and don't want to waste your time hunting for a Wi-Fi hotspot.
Budgeting your data is easy if you follow these tips:
Avoid using your cellular network for bandwidth-gobbling tasks. Skyping, downloading apps, and watching YouTube all eat up megabytes and can wait until you're on Wi-Fi. (You're on a Wi-Fi network when you see the symbol for Wi-Fi in the corner of your screen — it looks like a half-rainbow.) If you're lost and need to access a map and turn-by-turn directions, do so sparingly.
Keep track of data usage. Upon arrival, it's smart to start tracking how much data you're using. On your device's menu, look for an item like "cellular data usage" or "mobile data" and reset the counter at the start of your trip so you can see how many megabytes you've consumed. Some carriers automatically send a text message warning if you approach or exceed your limit and will let you upgrade your package without penalty.
Limit automatic updates in your email and other apps. By default, many mobile apps are set to constantly check for a data connection and update information. You can cut your data use by switching off this feature in your various apps. Start with your email: Go to your device's email settings and change them from "auto-retrieve" to "manual," or from "push" to "fetch." This means that you will have to manually download (or "fetch") your messages when you're on Wi-Fi rather than having them automatically downloaded (or "pushed") to your device. If you receive an email with a large photo, video, or other file, wait until you're on Wi-Fi to view it.
Other apps — such as news, weather, social media, and sports tickers — also automatically update. On some devices, you can select which apps are allowed to update via the cellular network. It's smart to disable these features in most of your apps so that they'll only update when you're on Wi-Fi.
Disconnect from your cellular network altogether. When you need to get online but can't find Wi-Fi, simply turn it on long enough for the task at hand, then turn it off again. Another way to ensure you're not accidentally using data roaming is to put your device in "airplane" or "flight" mode, and then turn your Wi-Fi back on when needed (this disables phone calls and texts, as well as data).
If you're traveling with an unlocked smartphone, you can buy a SIM card that also includes data; this can be cheaper than data roaming through your home provider.
Traveling with Electronic Devices
When traveling abroad with your laptop, you may be subject to export control concerns depending on the information stored on your laptop. Please review the Export Control requirements and contact your campus Export Control office to see if you need to take extra precautions with your laptop. Also, Ethics Compliance and Audit Services provides a webinar on Top Ten Things You Must Know Before Taking Your Laptop Overseas.
In addition, when traveling with any of your electronic devices, you may be a subject to a border search when re-entering the U.S. BEFORE you leave on your trip, please visit this UCOP FAQ Page that describes key U.S. Customs and Border Patrol (CBP) policies and your rights. UC Berkeley has also developed a helpful page on “Security Tips for International Travel”.
It is important to have a data security plan in place before you leave for your destination. Remember that information stored on your laptop can be at great risk for theft or corruption. If you are going to bring your laptop, use a small hard drive to back up information and keep them in separate places.
Encryption software may trigger import or export controls. If you are encrypting data, make sure that the software you are using is not going to cause problems at the border. Visit the Export Control page and contact your campus Export Control office.
Furthermore, the data you have stored on your device may require special precautions if it is subject to HIPAA Privacy and Security Rules. Prior to traveling, be sure to speak with your health center privacy liaison and campus privacy officials.
