Hi, I currently have a Pixel XL that I use daily. I need to use that phone for a week for something else. I still have my old Huawei Ascend phone. I charged it up and it started, so it still appears to work. I was wondering if I could pull the sim card out of my Pixel, put it in the Huawei and use it as my phone for a week, then switch back to the pixel? If so, what are the steps? Are there any gothchas I need to be aware of? I’m on the T-Mobile GSM network and I am on one of the My Choice Talk & Text plans.
