Help buy mom a new phone for work

So today I found out that the Xiaomi Mi A1 phone I bought for my mom with my bonus this past January 2018 got pilfered out of her bag while she was lunching with a friend in Greenhills. So she'll have to fall back to using an old, buggy and slow Lenovo phone for now. Money is pretty tight right now due to bills and other expenses but I would like to purchase another decent budget phone for her to use for work, probably the same model. Any help would be greatly appreciated and if I have any financial blessings in the future I will pay it forward.
