My Samsung J2 Pro which I have rooted currently support only one sim to be in 4g/LTE state at a time while other uses 2g.
When I change that 2g to 4g, first one becomes 2g.
How can I enable 4g on both sim at the same time?

It won't show 4G just HSDPA at maximum.
I have this problem for my sister's LG Optimus G E975. Not rooted. I've checked that the network (Smart Philippines) supports this phone with LTE with bands 1, 3 & 5. But all we get is HSDPA. I've tried *#*#4636*#*# to manually select LTE only then network unavailable. I don't know how to fix this. Well clearly Im really new here so I hope someone helps. Thanks.
I know in that specific area where my sister tries to detect 4G, there's 4G because I have my Nexus 7 LTE, same network. I do detect 4G connection.
I believe special sim card is needed, which supports LTE. I have one old sim about 4 years old, it does not show 4g networks, if i switch sim, which was sold as 4g card, it shows LTE networks on the same phone.
Maybe you should contact your service provider about that.It is also possible where ever you are,there is no 4G coverage.
Hello i have a Motorla Razr XT926 Verizon ( this was designed to also be used on the LTE network 4G on Verizon
Im in the Uk and have a 4G LTE simcard the network is EE Orange and T-Mobile
It automatically goes on 2g & 3G H+
however does not allow the 4G gsm simcard to provide a the 4G network. I want to confirm that its not my provider as If I put this in another 4G handset the LTE nework is 4 to 5 bar signal strength
I have been in network work settings selected global & also GSM/UMTS and done a manual network search no 4G is to be found
I have contacted Motorola who advise that possibly it does not work on GSM simcards only on CDMS
Is there anyway of providing a solution to allow the LTE 4G to be used I presume something to do with the hardware ?
Please expalin in simple form
Many thanks

I've bought a Galaxy S7 duos and have realized that the second sim only supports 2G.
Here in Japan there is no 2G network, only LTE and UMTS. Can anyone suggest a dual sim phone which supports LTE/UMTS on both sims?
I tried using engineering mode but it doesn't work on my mobile . I have Samsung exyno's processor. I want to unable the LTE band ASAP. Plzzzzzzz HElp me:crying: :crying:
The lte variant is different to the 3g one and has a qualcomm chip for lte that isn't present in the none lte version. Pretty sure it's impossible to do
you can not use jio 4g on a 3g phone because jio doesn't have 2g or 3g fallback network.
not answer but query... facing same problem. with my samsung galaxy note gtn7100 3g.
is updating by rooting the phone to lollipop or other version will bring 4g accessibility or not ?
As with new software updates Mi A1 (sd625) and Redmi 5(sd450) are getting dual volte feature, so why can't we?
Even with qualcom snapdragon website our sd820 supports dual 4g at the same time, so why can't we even get one sim for volte(calling) and other sim for 4G(data only).
As in HTC phones if we change data sim, it doesn't change network preferences, like we can use data on 2g sim, and other sim remains on 3g network. Can't we use this kind of thing? Where1 sim will be on 4g volte network, and on other sim we use data on 4g/3g network.

Yes we have Lte on both sims but not ate same time, one time only one sim remains on 4g network and other goes on 3g/2g. But as per Qualcomm snapdragon our sd820 supports dual sim 4g at the same time. Volte on both sim is a different thing, but still want answers for that also.
yeah ! bro same problem here!!!!!!!!!!!!!!!!!!
Any dev wants to invest some time in it ??
Any possibility of getting dual 4g ?
Maybe sd820 supports dual lte but i think that it maybe more of device specific.... I think our device hardware doesn't support it even if chipset is compatible
Its a modem feature and our device's modem doesn't support it so I don't see that coming.
