Caught maid with mobile phone

I have never allow my maid to hold a mobile phone, the reason is because i see so many maids talking non-stop on the phone while taking care of children or doing housework. Sometimes i see them gigging over the phone, crying over the phone, flirting on the phone.. how can they managed the tasks when they are on the phone, not many ppl can multitasking.
1st time caught my maid with a phone just come over. I gave her my warning and keep the phone and phone card with me till she returned home for holiday last year.
2nd time caught my maid with a phone was like 2 months ago, where she brought janelle to the playground. i hide myself at a coner and see what she was up to with janelle at the playground. Janelle was pushing her walker and she had a fall while maid was on her phone smsing. She bended down and with one hand hugged janelle and another hand still on her phone. She dont even noticed me walking towards her. When i called her, she was so shocked and quickly keep the phone away. that time she says the phone was her friend, and she returned the phone to her friend infront of me. I got a big scolding and reasoning from me that day.
this is the 3rd time i caught her on mobile phone again, she was smsing when i walked into her room with janelle. this time round she was so shocked and wanted to cry out, i see tears around her eyes. I keep quiet, no scolding, nothing, just asked her to bring janelle to wash up and to the bed. I took away the phone. After Janelle is sleep, i gave her chances to tell the truth. When she tried to lie to me, i took her to the living room and i on the CCTV.. then she spell all out. Hope that is all she hid from me. the reason she gave me why she need a phone was, to sms her friends and family in indo. The sim card is giving 75sms free for every 5 sms sent. and to listen to music and also as a alarm clock. I was too tired to saying anything else that time, so i told her i will keep the phone while let me think what's the best solutions.

I put myself into her shoes, in today's world mobile phone had becomes one of must have item in our daily life. Everyone need to stay in contact with friends and family, especially when out of town. Take away her mobile phone = cutting off the connection with her friends and family.. this is not a good thing to do. But for me to give in to let her be those maid that i saw downstairs, chit chatting non-stop on the phone when taking care of janelle, is a NO NO for me. Cracking my brain for a solution that has the best of both world.

My proposal to her and she had accepted it happily.
- She is allowed to use mobile phone, but only in the night after Janelle sleep - about 10pm till next morning 7am.
- in between 7am to 10pm, she is not allow to keep her mobile phone as who knows if she would use it secertly anot. she will need to pass the phone to me and keep it in a the glass cabinet where i can see it.
- i have every rights to know who she is calling or smsing to.
- day time, no more taking nap with janelle, once janelle is asleep, she is to do up all her housework.

Guess this is the best i can do for her. If she let me caught on her lieing to me, sorry but i have to sent her back.
