Do both SIM cards support 4G?
Yes both 4g enabled sim cards will support 4g in J700F model.
Just not at the same time
If one Sim works In 4g the other will have a 2g connection. but this can b interchanged
Can I enable both sim 4g at the same time?
no

No. One can be used in LTE another in 2G

How come Sprint doesn't use a sim for their LTE? Is the sim even necessary or is to bring global usage to the Verizon version?

The SIM card is used for 4g. 3g and voice is over the cdma radio. And sprints does have a SIM if I'm not mistaken it's internal tho and cannot be accessed.
The biggest problem with the "non-removeable" sim setup that Sprint uses is you can't just pop it out & stick it in another phone.
I do this all the time with my VZ sim card.

thats for sprint? it looks like verizon its all handled through the sim for both lte and 3g.... right?
As far as I know its just the lte that needs the SIM. Now of course the phones are made to not function w/o them but I'm pretty sure it's only the 4g that actually relies on it
I accidentally bought a US Cellular Galaxy SIII brand new. But turns out, there is no coverage anywhere close to me except for Roaming on Sprint. So can I activate A VZW sim on a broadband plan for a galaxy tablet and then put it in my phone? Can a cricket 4G sim work in it? It is a CDMA phone that takes a 4G sim and I really want to use it.

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

If your device doesn't support 4g then it's no use trying to get it to work. Manufacturers ship various different models of the same device; what happens is you probably did not get a variant with 4g support.
Fortunately, you dont need a 3g sim to use 3g. 4g sims in general are made to support all signal technologies up to 4g so 3g works too.
...alternatively it could just be that you are on an area with poor 4g coverage and your device ends up sticking with 3g

Can anyone let me know if the S8+ Dual Sim is 4G/3G as Australia is turning off all 2G networks.
Thanks
It's 4G/3G/2G (SIM 1) + 4G/3G/2G (SIM 2).
TL;DR: LTE/LTE.
Pretty sure that SIM 2 is GSM only

Both SIMs are 3G and 4G, but you can use as 4G only one and the other one will be max 3G, or if you prefer can be 2G as well. This is not so relevant, since you switch the SIM cards for internet use (since you can not use both cards in the same time for data usage) it will change settings to 4G for the preferred SIM immediately.
