Those of you who have Movistar mobiles will probably already have voicemail set on English, but a friend of ours recently told me that she never used voicemail because she couldn't understand the Spanish lady when she rang 123 to listen to a voicemail. So, just in case anyone else is in the same situation:
If you miss a call and someone leaves a voicemail message, Movistar send you a text message informing you and telling you to ring 123 to retrieve it. Calls to 123 are free.
To change to English:
That's it - done.
The options when you ring 123 are:
1 Check for messages
2 Change your greeting
3 Change your mailbox settings
1 Enable the quick menu
2 Change your code
3 Be notified of a message by a call to your mobile, rather than a text message
4 Change language
When you ring 123 and press 1 to check for messages, your options after hearing a message are:
7 Delete message
8 Ring the person who left the message
