Single Sim No MicroSD. Great cheap phone. Cheaper than Chinese sellers and with faster delivery from Shopmonk. Personally they say 14-21 days but I received my last order of Bose QC35 in 4 days from order DHL Express. Faster than Australia Post! Also 1 year warranty with Shopmonk.

Might want to emphasize it's a single SIM phone without an MicrosD card slot, for those who are wondering why it's so cheap. so you'll be stuck with around 10 gigabytes of user accessible storage.
