Certification is an important step before a phone can be made official and the Huawei P20 (“Emily”) and P20 Plus (“Charlotte”) are almost ready to take that step. They appeared on TENAA, though in name only.
They were submitted for licensing, with the code names shortened to three letters – EML and CLT. These devices will be tested for both GSM and CDMA compatibility as is necessary for a launch in China.
Then there’s this model – ATU. That’s “Anne”, perhaps, the code name for the Huawei P20 Lite.
