What are the basic differences between iMessages and regular text messages (SMS)?

There are some basic differences. Here are some of them:

  • Unlike the text messages, iMessages offer a lot of extra features, for example:
    • you can share your location
    • you can know when your message is delivered and then read
    • you can include message effects: bubble effects, camera effects, full-screen effects, and handwritten effects (see also: iMessage effects not working?)
    • Messages will have timestamps
    • you can see when your recipient is typing in real-time (read receipts not working?)
    • you can have no character limits (SMS messages are limited to 160 characters)
  • One really good thing about iMessage is that iMessages are always encrypted while text messages are not.
  • iMessages appear in blue bubbles while text messages appear in green bubbles. This is Apple’s way of letting you know that you’re sending an SMS text message (green) or an iMessage (blue).

Does iMessage use my data plan?

Yes, it is possible. By default, iMessages will be sent over Wi-Fi. If your device is not connected to a Wi-Fi network, that means that iMessages will be sent over cellular data. This further means that cellular rates may apply. Text messages don’t count against your data plan. However, depending on your cellular carrier (e.g., Verizon, AT&T etc) a charge of per-message may apply to messages sent and received. But these charges are usually minimal unless you are sending too many messages. Some data plans have unlimited messaging for no additional charge.

Multimedia messages (photos, audios, and videos) may use data. If you are just sending texts, they are really tiny, but if you are sending photos, videos in text messages, they may consume much more data.

It is important to estimate your data use. You can do that with your iPhone. iPhone can le you know how much cellular data iMessage uses. Here is how:

  • On your iPhone, tap Settings
  • Tap Cellular
  • Find the Cellular Data section
  • And find the System Services option
  • Tap System Services
  • Find Messaging Services.

As you can see, in this example, Messaging Services” (iMessage) has used 106MB from the last time these statistics are reset. You can reset this by going to Settings > Cellular and scroll down and tap Reset Statistics.

Does iMessage work internationally?

Yes. iMessage works anywhere in the world as long as you have an Internet connection. In fact, it can be said that iMessage can be the best option to use when traveling overseas, especially if you want to avoid roaming charges. You to send unlimited texts over Wi-Fi and a lot of places now offer free Wi-Fi: airports, cafes, busses, etc. Furthermore, international roaming text messaging rates may be high.

This means that you can send and receive messages without the need for an international data plan, which could be difficult (even impossible) and/or expensive to get.

Does iMessage work without Wi-Fi?

Yes. As stated above, if you do not have a Wi-Fi connection, messages will be sent over your cellular network.

Can iMessage work on Android devices?

No. Android devices (e.g, Galaxy, Pixel etc) can’t use iMessage. This means that Android users cannot enjoy the cool features of iMessage. If you send a message to someone with an Android device, the message will be delivered as an SMS/text message. Effects and emojis, thus, may not work.

Can iMessage work in Airplane Mode?

Yes. You can send and receive iMessages when you’re connected to in-flight Wi-Fi, even if Airplane Mode is enabled. Here is how:

  • Tap Settings  and turn on Airplane Mode
  • Turning on Airplane Mode will disable Wi-Fi
  • Go ahead and enable Wi-Fi by going to Settings > Wi-Fi
  • Connect your device to a Wi-Fi network (e.g., in-flight Wi-Fi)
