Does anyone know how to use jio SIM on tab 3 7 or how to active engineering mode
Reliance Jio is a CDMA/LTE operator. They do not have GSM or UMTS towers. Only CDMA and LTE devices can work on their network.
You will need either a CDMA capable Galaxy Tab 3 variant (SM-T217S, specifically designed for Sprint in United States and will generally be SIM locked), or an LTE-capable variant supporting India's LTE bands.
Jio does not offer GSM or UMTS services. If your Galaxy Tab 3 variant is a 3G/GSM variant, it can never work with Jio.
As an addendum, you won't be able to use SMS with Jio if you use a compatible LTE device that isn't also CDMA. GSM-based LTE devices can only send SMS over LTE when connected to LTE operators that upgraded from GSM and UMTS, or if both the network and device support VoLTE.

im really lost in the terminology behind all of the different phone standards... umts/hspa/gsm/evdo/1xrtt/lte/wimax/etc etc etc...
Verizon (and Sprint) are CDMA dominant networks. But Verizon LTE requires a SIM-card:
(1) Will a Verizon LTE phone accept a GSM SIM and work at optimal speed? e.g. Vodafone SIM in UK
(2) Conversely, can't the "Global/GSM" Galaxy Nexus take the Verizon LTE SIM and work on Verizon's network?
(3) Is the Verizon LTE's version of Galaxy Nexus a hybrid CDMA-GSM phone (like Sprint's Photon) ... i.e. if I get it unlocked, I could also use it with most international services?
The unlocked global GN is 750$. But if Verizon's contract price is 300+200 [term. fee]... AND it works internationally... clearly its the way to go
1 - No.
2 - No.
3 - No.
You're confusing SIMs for radios. Each phone has a different radio that can connect to EITHER GSM (UK model) or CDMA (USA model). The GNex cannot connect to both.
The GSM version will work in the US with a T-Mobile or AT&T SIM card on a GSM network. You can also take it on international trips (changing SIMs or roaming), as most of the world uses GSM.
The CDMA (Verizon LTE) version will work on Verizon only.
So after having bought and upgraded the phone for the gf and having seen the amazing display and speed, I'm considering getting one for myself (even though I'm a bit hesitant due to the battery life and:
From what I've seen, it looks like this phone is compatible with:
Metro PCS for and T-Mobile for 3G and Sprint for 4G, I think. (US carriers)
Because I'm really green when it comes to this, I'd like to know: GSMArena lists the 3G network as HSDPA 2100 while Metro PCS for and T-Mobile is listed as carrying the 1900/2100 bands for the 3G network, but doesn't specify what type (eg HSDPA, EV-DO, etc). Does this matter? Like, would the phone not work even though it can tune into the 2100 band because of type?
While on the subject, does anyone know whether or not they'll add more LTE bands to USA carriers? The only US 4G carrier I saw that carries the 800 band is Sprint, which I heard wasn't very good and also don't have compatible 3G bands.
Also, the 2G network (which I'm assuming is voice calls only) for the phone is listed as operating under CDMA 800/1900 bands. Would these bands, the CDMA, work for US carriers? or would it need GSM?
Thanks!
PS For USA users who've managed- how's the phone work with USA carriers?
Since gsmarena states that it has gsm 2g bands
just found this article on mobile syrup explaining that bell is going to be decommisioning their cmda towers in january 2017
http://mobilesyrup.com/2016/08/15/bell-cdma-canada-2017/
will this affect oneplus 3 users because i heard that this phone uses CDMA networks
if the oneplus 3 operates on CDMA wont this affect bell and virgin mobile users?
EDIT:
The OP3 North America model supports
WCDMA: Bands 1/2/4/5/8
FDD-LTE: Bands 1/2/4/5/7/12/17/30
CDMA EVDO: BC0
So once bell shuts off this network the OP3 should be able to operate with WCDMA and FDD-LTE
Bell hasn't really been using their CDMA network for awhile now. They have been using GSM phones for quite some time now and slowly made the transition for those who were still using CDMA phones.
So, nothing to worry about here. Bell is just making it official that they are shutting down their CDMA network.
Moto Z2 Force (USA AT&T UNLOCKED) doesn't have LTE with any Venezuelan SIM provider
Hello i will do my best to try to explain my issue.
I bought a Moto z2 Force x (At&t) unlocked in EBAY, here in Venezuela i used in Movistar (3g band 1900 / LTE band 4 1700/2100)
The phone dont work with LTE , only 3g (it show 4G logo in signal bar, but not 4g LTE) .
if i do *#*#4636#*#* and enter in network hidden menu, and put in LTE ONLY, the phone enter in NO SERVICE.
I have tried Digitel (3g Band 900 / LTE band 3 1800) , same thing, only takes 3G, if put on LTE ONLY, no service.
In settings, networks, movil networks, preferred network type are only 3 options ( 4G Recommended, 3g, 2g).
I put a Verizon wireless sim card and the options change in the network menu (Global, CDMA, LTE,GSM,UMTS), but no signal because im here in venezuela, of course.
If i put a AT&T the menu totally changes, put ad LTE, LTE ROAMING, VOLTE...
What can i do with my phone to enable 4G LTE Bands? Why my phone is not working with LTE normally? It is software issue? At&t stuck phones to dont work with LTE with foreing sim cards?
Im very confused because if i put Movistar and Digitel SIm cards in LG g6 H873, Moto G4 Amazon PRime, Xiaomi Redmi 6, all the phones takes 4G LTE in seconds.
I hope some of you have the correct answer. Sorry for my bad english, i've did my best
