HOWTO: Change language on Android
This seems like an extremely useless tutorial but it will be helpful for those who travel and use foreign SIM cards.
The first thing that happens on your Android when you plug in a new SIM card is that it asks you whether or not you want to adopt the settings on the SIM. You should accept the changes since it’ll automatically update your settings to use the local networks for voice and data. You could always, of course, find instructions online or to cross your fingers that your pre-existing settings work but the safest and the laziest way is to just let the machines do their ‘g-thang.’ Using this option though will also change your Android language settings to the native language of where you purchased the SIM card.
You’ll want the below instructions to help you navigate your Android to change it back to your language:
1. Menu button
2. Gear icon (goes to Settings)
3. Scroll down to the white block with the letter ‘A’ (goes to Locale and text)
4. First option (goes to Language)
