Re: Dual sim
I took a punt on the Umi Zero a while ago. It is not 4G, so if this is a necessity look elsewhere.
It meets my needs perfectly, can manage and name each sim separately, eg., work and personal. Manage the contacts to dial accordingly or ask which sim to use. One sim can be removed and a memory card installed instead.
Only downside is the deliver time it took to come from China
Oh, and she that must be obeyed liked it so much she has purchased one also. So far ( six months in, I have had no issues)
Hope that helps a little
