[Q] Dual sim phone with 3G + 4G

Do you know a phone that has dual sim and has support for 3G for one sim and 4G for another sim simultaneously ?
Or 4G support for bought sims ?
And it should be available in Europe

SM-G930FD on Rogers network

Hey,
So I purchased the SM-930F on ebay, I ended up with the FD model. So first question there, I couldn't see any difference between the F and FD in the specs I looked up other than the hardware allowing an additional SIM. Is there any reason why I should be concerned about an FD over an F?
Second question; I checked the frequencies before I purchased and I should get LTE on the rogers network however I only get 3g and HSDPA+ or 4g occasionally but rarely. Why am I not getting LTE?

Thanks!

Can you please post picture of a sticker with exact model name (you can blur or wipe IMEIs of course)?
And a screenshot of Settings -> About device -> Software info.
Do you have 2 different IMEIs?

Screenshot 1 - IMEI
Screenshot 2 - Software Info
Thanks mate

First screenshot confirms - you got dual sim configuration With 2 different IMEIs. The other one shows you got proper firmware with (probably) Vietnam regional code. No problems so far.
SIM Slot 1 is compatible with 4G, 3G or 2G networks, while SIM Slot 2 is compatible with 2G network only. I believe you can change it via menu, but out of two sim cards - one is always 2G! So be sure that your sim card in a corresponding slot. Check with operator that your sim card is 4G capable. And last thing - check the 4G coverage at your place.
Also different regional codes firmware shows different signs on LTE networks - some shows LTE and some 4G. You can check type of network with Network Signal Info or similar free programs from google playstore
Do you mind sharing ebay profile where I can buy dual sim Galaxy for the price of single sim?

I have been using it in my condo in downtown Toronto, I always received good reception on my Canadian S6. For some reason with this S7 my reception continues to be HSDPA.
WIth the FD model the 2nd sim goes where the MicroSD card goes, as I have an SD card in there I know I have the sim in slot 1. Still can't work out why I wouldn't receive decent reception.
Here is the link, as I mentioned I ordered an F model however I received a FD model

Dual SIM 4G+3G or only 4G+2G ?

I'm contemplating a purchase for a Mate 9 with dual SIM capability ( from Kogan Australia). It's advertised with dual SIM. For me, the secondary SIM would only add value if I can use it on 3G, while I keep the main SIM on 4G.
But in some documentation, the secondary SIM only supports 2G. Has anyone successfully used Mate 9 with 4G+3G SIM combination.

For sure....! I also think 4G+4G can work...

If the Australian version is the same as the European version it will support 2G, 3G and 4G on SIM 1 whilst SIM 2 will support 2G and 3G.

3G would be great on SIM 2. The problem I'm trying to solve is that our Australian telco ( Optus ) has severely degraded its own mobile network, to the point where we can't receive voice calls anywhere in our suburb. LTE used to work well, not any more. On the other hand, they improved somewhat on their 3G network. My wife is still in contract with cheap plan. So I could arrange a dual-SIM where SIM 1 is on 4G with another telco, while SIM 2 stays at 3G with the old telco. Things may improve for their network, or the company is going down, we shall see.

4G/3G is how it does it.
Both will support 4G but you'll need to put the switcher setting on your homescreen so you can switch quickly - you can't have both on 4G but both will support it. The other will be able to use 3G.

No data for NTT Docomo sim

I've been using the oneplus 7 pro fine for the past two weeks in Singapore and Hong Kong on local carrier sim.
Returned to Japan today and noticed I couldn't get cellular data after setting correct APN. Have tried switching to 2g/3g but no luck. The Docomo sim works fine with 4g signal when i put it back on my oneplus 6.
Any ideas?

Model was bought from oneplus US online. Model GM1917

Which model/firmware CSC code are you using? Can you still connect on 5G with non-roaming sim cards?
