[Updated May 2013 with new AT&T screen shots and prices]
Travelling with your AT&T iPhone to Europe? Here’s how you can make sure it works when you get there and avoid a giant bill when you get back. Who doesn’t like to save money?
If you haven’t done so already, register with AT&T’s web site so that you can make changes to your phone plan options online. Log in with your wireless number and password, so that you get to the home screen for your wireless service. Look in the top-left quadrant of the page for a menu called “I want to…”, which will look like this:
Click on "Add or change services", and you'll get a long screen showing all your current wireless settings that don't have to do with domestic US voice minute bundles. You can ignore most of these (i.e., leave them unchanged) and scroll down to the section titled "International Services". It should look like this (depending on your current settings, you might have different items selected):
Now, let's walk through the settings that will ensure you hit the ground running the moment your arrive in Europe. Straight away, we're going to ignore the first two sections called "International Long Distance" because that's about calling and texting overseas when you're still in the US. So skip this section.
The next section is important: "International Roaming - Voice". Select "Standard International Roaming" - this turns on your ability to "roam" (connect) to other carriers' networks when overseas. It's free, but turned off by default for fraud protection reasons. Next, move on to...
This section allows you to pre-purchase text message packages of 50, 200 or 600 texts. You pay for each text sent when roaming, and receiving texts is always free. The larger packages give you more discount per text. Note that the packages are pro-rated over the billing cycle. So if you turn on the 50 pack for 15 days in the billing cycle, you'll only get 25 texts. Compared to a one minute call, texting is one fifth the price: you can send 5 text messages. If you are a text maniac, I'd suggest toning it down for the vacation and letting your BFFs know you're paying for every text you send.
There are a whole host of options here at different price points. Let's face it, international data roaming isn't cheap -- but prices have come down more than 80% in AT&T's latest revision to its pricing. To save you doing the math, here are the per-megabyte costs for each of the options listed in most European countries:
There is no "overage rate" -- if you exhaust the data plan, you simply cannot use data any more. This prevents a nasty surprise in your next bill if you download a lot of data.
If you forgot to buy one of these options before you left, AT&T gives you one very limited shot at retroactively buying data options during your trip. You can back date the feature to your last billing cycle start date. You have to know when that is to see if it might save you from excessive charges. If your billing cycle start date happens to be the day before you got back from Europe and you only log in when you get back, for example, you're out of luck.
If you mess up, scroll down to the bottom of the page and click on "Reset". If you're done, scroll down to the bottom of the page, and click on "Next".
The screens that follow are pretty confusing, because the system splits out each feature you're ordering, and in some cases lets you backdate or set a future date for your changes for each feature. Read the page carefully to see which feature you are setting up.
Backdating (if available) is really handy if you want to retroactively add global text messaging, for example. But at the moment, we haven't even left the US yet, so you probably want to select "Make effective/expire today" or "Future date to the next bill".
"Future date" sounds good but is actually very limited. It only allows you to turn on your settings on the date of the next bill -- which may not be near the time of your trip. "Make effective/expire today" means your changes will be complete and active on the AT&T network within the next 12-24 hours. I'd recommend you make all your changes a day or two before you leave for Europe and just make it effective that day.
One "gotcha": some features like Global 50 text messages and Global data are pro-rated during a month if you don't turn them on at the beginning of the billing cycle. For example, if you turn 50 international text messages on half way through the billing cycle you'll only get 25 text messages during that monthly billing period. Gotta love that, eh? 🙁 That's another reason to use the "backdate" feature, because you can set a feature to start at the last billing cycle, then set it to expire at the start of the next billing cycle. That way you are sure to get 100% of the text or data bundles.)
When you've set the effective date for each feature, click on "Next". When all dates for all features have been set, you get one final chance to review all your changes and read the small print of the services. If all is OK, click "Submit". If not, you can cancel or go back to previous pages. If you messed up a date, click "Back" and correct it. Once submitted, AT&T will send you an email confirming your changes and you'll be ready to stay connected as soon as you hit the ground.
To control data usage, use the iPhone Settings app to turn data roaming on or off (Settings->General->Cellular). Apps can still run in the background and access the network without your knowledge, so the only effective way to control network usage is Settings. Do this before you take your iPhone out of "Airplane mode" to avoid inadvertent data charges.
Turn your iPhone on after arrival and, after a few minutes of searching, it will automatically connect with one of AT&T's roaming partner networks in the country you're visiting. You typically get a free text message from AT&T advising you of data charges and maybe a text from the local network operator telling you about any features or charges.
Unanswered calls to your iPhone go to US voicemail will incur per-minute charges. The call actually makes it all the way to your phone in the foreign country and then is forwarded back to your voice mail number the US -- hence the charges. You can avoid this by turning on "forward all calls to voicemail", so that the call never reaches your phone in the first place (this means no-one can call you directly, but you can still listen to the voicemails they leave). The other option is simply to turn off your phone when you do not want to be reached -- then the call never reaches your phone either and goes straight to voicemail.
To send all calls to voicemail, dial *#67# to see which number is used for your voicemail. Then dial *21*[number]# to forward all calls unconditionally. Then, when you want to turn this off, dial ##002# to restore default call forwarding.
Important: log back into the AT&T site and reverse the changes you made. Do not use the backdating capability for the "turn off" date, otherwise you risk erasing the benefits you got from choosing discounts ahead of time. You can use backdating for the "turn on" date if you forgot to order something before you left.
Enjoy your trip!
