When you move your SIM to another phone, you keep the same cell phone service. SIM cards make it easy for you to have multiple phone numbers so you can switch between them whenever you like. In contrast, only SIM cards from a specific cell phone company will work in its locked phones.

Since international roaming rates with your current phone and U.S. network can be high, buying an unlocked phone for overseas travel can save you money. It can be as easy as purchasing an unlocked phone in the U.S., traveling to your destination country, and purchasing a local SIM card.

Prepaid TravelPass lets you use your prepaid talk, text and data* allowances while traveling outside the US. It’s available for $5 or $10 per day, depending on the country you’re traveling to. To learn more, visit the Prepaid TravelPass FAQs.

Here’s how.

• Use your mobile phone. This is the easiest option.
• Get app-happy. If you have a smartphone or tablet, you can make calls at extremely low costs by downloading a Voice-Over-Internet Protocol (VOIP) app.
• Switch your SIM card.
• Get a temp.
• Use a hotspot.
• For determined luddites only.

If you can’t get an international plan for your destination, the safest option is to turn off data roaming entirely. In iOS, the toggle switch is under Settings > Cellular. In Android, it’s under Settings > Wireless & Networks > Data Usage.

Standard text messaging charge of $0.20/message applies to messages sent and received in the Nationwide Rate and Coverage Area, except for International Text Messages, which cost $0.25/message sent and $0.20/message received, and which do not use messaging bundle allowances, unless you are on a MORE Everything plan …

DO NOT send SMS messages or text messages while traveling overseas unless you want to pay out the nose for them. (Also remember that it’s usually not possible to send SMS over Wi-Fi.) You CAN receive SMS messages/texts, but you might pay for them. You CAN receive messages (non-SMS) over Wi-Fi, for free.

(On iPhone, tap the “Settings” icon, tap “Cellular,” then turn off “Cellular Data.” On Android, tap the “Settings” icon, tap “Network & internet,” tap “Mobile network” and turn off “Mobile data.”) After turning off mobile data, you’ll still be able to make and receive phone calls and get text messages.

When you keep your mobile data on then it effects your battery and the background apps which go on syncing. When your mobile data is on, your location is at high accuracy, which again drains your battery life.

Cellular data has nothing to do with you making a phone call if it’s switch on/off. Cellular data helps you to connect to the internet. You can still make phone calls even if it’s off.

Traditional texts (SMS, MMS) can only work on the cellular network and will not work on Wifi. If they are working on wifi it means it is connection to a data based messaging service like imessage, whatsapp, facebook messenger.

The biggest difference between SMS (Short Message Service) and MMS (Multimedia Message Service) is that SMS is only capable of sending text. MMS can send multimedia content—pictures, video, and audio—in addition to text.

Android Offline Messaging Apps can send a message without the data connection. Offline messages are the best solution to get your messages delivered even if you have trouble with net connectivity.

The steps to send WhatsApp messages for free without data are simple: just turn off the data connection, compose and send a WhatsApp, then turn the data connection back on, and keep toggling it on and off and the message is delivered.
