AT TIME OF THIS POST UPDATE - NEITHER H818P nor H818N SUPPORT **SIMULTANEOUS** 3G/4G CONNECTIONS ON BOTH SIMS AT THE SAME TIME. ONE SIM ONLY! Keep reading below.

CONFIRMED:* H818P Does not work on Band 28 (700Mhz)... only Band 17. This has been confirmed by LG UAE. See my post here: http://xdaforums.com/showpost.php?p=62204877&postcount=533

* May 2015: LG announce at least two G4 *DUAL SIM* phones to be released with their latest flagship single-sim model to be released simultaneously (or within 1 month) after most market single-SIM release dates. The 2 most common models areH818P (Ukraine, Thailand, Malaysia, Indonesia, UAE)] and the H818N (Hong Kong, China)

* (CONFIRMED) H818P model supports 3G/4G data connection on SIM1...It is ALSO supported on SIM2 (provided SIM 1 is set to 'GSM only' (or vice versa). It can be a bit tricky for some to get it working, here's how to do it: http://xdaforums.com/showpost.php?p=61621397&postcount=165 You can also see the functionality for BOTH sims from a user screenshots HERE: http://xdaforums.com/showpost.php?p=61115881&postcount=49

* (CONFIRMED) H818N model supports 3G/4G data connection on BOTH SIM1 & SIM2. Thanks to [MENTION=6802272]Neutrality[/MENTION] here: http://xdaforums.com/showpost.php?p=61674683&postcount=188 If you cannot enable LTE/4G on SIM 2, you are likely using an old software version (v10c or earlier) meaning you will need to access the hidden menu from the dialler. Open the phone dialler, type in 277634#*# suggested by [MENTION=311257]Syrop[/MENTION] on page 18. who STEPS you through activation: http://xdaforums.com/showpost.php?p=62100690&postcount=460. If you have v10d, the option to choose 3G/4G on SIM2 should be readily available in normal menus. See [MENTION=1561478]kanzone[/MENTION] s post here: http://xdaforums.com/showpost.php?p=62307988&postcount=572 and the one above it.

* Out of box,

wireless charging is NOT supported

on DUAL SIM models, as SIM2 is roughly in the position where the contact pins are. NFC capability is retained.

* H818P supports 4G LTE band 17 which is 700Mhz (not not Australia/NZ and other band 28 countries on 700Mhz). H818N does not support 700. [MENTION=4420850]bahamot_zero[/MENTION] confirms on page 2 with sticker/box image: Same with [MENTION=6725480]Icewanted[/MENTION] page 4
