You’ve seen how to use 回 to say sentences like 今天晚上我不回家 . 回 can also mean to return a call or to reply to an email.​
他会马上回你的电话。
(Tā huì mǎshàng huí nǐ de diànhuà.​) He will immediately return your call.​
我还没有回你的电子邮件。
(Wǒ hái méiyǒu huí nǐ de diànzǐ yóujiàn.​) I still have not replied to your email.​
你为什么不回我的短信?
(Nǐ wèishéme bù huí wǒ de duǎnxìn?​) Why didn’t you reply to my text message?​
Which tone is that?
Here’s another example of a character that changes tone based on the word it’s in.​
发
​头发
(tóufa​) hair​
发现
(fāxiàn​) realize​
发短信
(fā duǎnxìn​) send (a message)
