duel sim difference? - Samsung Galaxy Note 9 Questions & Answers

Just wondered has anyone tried swapping the sim tray on a single sim note for a twin sim tray and flash the duel sim software?

No. Even if the phone had two SIM readers, a dual SIM version would have an unique IMEI number assigned to both SIM slots; single-SIM phones only have one IMEI number.

Anyone tried a dual sim adapter with the R1 HD?

I have an older dual sim adapter I had used on some previous phones. I installed it primarily out of curiousity on the #2 sim slot and populated it with two freedompop (AT&T LTE, data only) sims. Sim toolkit (the app used to switch sims) shows a notification ("AT&T sim-1), but doesn't allow me to change it. It may also be reading sim #1 in the phone since it is populated with a tracfone AT&T sim, as oposed to one of the freedompop sims in the adapter on the phones #2 sim slot.
It is picking up one of the freedompop sims with LTE and seems to be working fine, I just can't access sim toolkit to change freedompop sims.
Anyway I was wondering if anybody with experience with dual sim adapters might have some insight on the adapter use with a dual sim phone. Thanks.

Dual sim but only 1 carrier for data

I have a dual sim N9 from Globe Philippines. I just realized that despite it being dual sim, only the slot where the Globe sim card is placed can access data. I want to be able to choose which sim card I'll use for data. There are places where signal is better for the other brand sim so it's only logical to shift to that carrier's service. Is there a way to do that without having to sim unlock the phone?
