Some Questions on the M8 Dual Sim

Hi!
Can anyone confirm
1) the SIM 2 is 2G only, and not 3G.
2) what the bands for 3G on SIM 1 (in case the places I'm traveling to do not support LTE on band 3 and 7, 1800 and 2600, and I need to fall back on hspa)
3) Since its Dual Standby, when I'm surfing on the phone (data from Sim 1), will a call coming in on Sim 2 ring/get through?
4) Related to 3). If I'm using the phone as a mobile hotspot or USB tethering with the data from Sim 1, will a call coming in on Sim 2 ring/get through?
Would really appreciate if anyone can shed some light on the above.....
Thank you

Hi!
1) Yes, Sim2 only 2G
2)SIM1- GSM,WCDMA, LTE (I'm using band 3)
3) Calling has priority, you will receive call on SIM2, data on SIM1 will be interrupted until you talk on SIM2
4) Same as in 3), until you talk on 2 no data on 1

Tnx guys..

P6 S - U06 known issues

Hi, I am an owner of this very nice smartphone, I'm very happy with it but there are a couple of problems that I'm not able to fix:
- it is sold as a 4G (LTE) phone for the sim card on the main slot and 3G on the second slot, it works only on 3G network for the main slot and 2G for the secon one
- an annoying metallic voice or strange noise when I receive or make a call from/to some numbers with a specific sim card (it's random but always the same numbers, I mean... not all numbers of a specific carrier but only some numbers of that carrier and never, till now, with other carriers).
It occours when that sim card is in the second slot (2G) or in the main slot and I force the 2G network on the main slot.
Did you experience the same problem?

Which ever version of the phone that you get is not able to do 4G or LTE so thats a scam of the carrier and for the noise im not sure what can it be.

Vendor assured me that the phone can go in LTE... I must investigate which frequency use Vodafone in Italy.

And if you can search the web you can see for your self that P6 does not support lte in any way.

Thats what I'm trying to explain all the time.

You are probably right and it isn't an LTE device... but for sure the specs on gsmarena are wrong when they say it is a dual sim dual standby.
It is dual active, I can receive calls on the second sim while I'm engaged on the first, hold this and answer on the second and vice versa.
On huawei.ru they say it is 3G, no P6S found on huawei.com.cn

Yes, you are right about dual sim specs. It is definitely dual active.
On GSM Arena are practically all phones dual sim standby. But this is wrong. However, we must admit the fact, that dual sim active phones are very rare.

[Q] Data from both sim cards?

I am in search of a dual sim phone, and I consider the zenfone 2 a good candidate.
However, it is vital to me that the phone can support a data connection from both sim cards.
Obviously not at the same time, but to switch data connection from one sim card to the other, without having to physically change the sim cards around.
Is this possible on the zenfone 2?

This is possible but sim2 only supports 2g speeds.

Thanks, that's quite a disappointment.
I thought today most other dual sim phones do support 3/4G on both sims?

AFAIK there is no data from sim2, not even 2G

.
You will not get data on sim 2 due to Asus blocking it with their firmware. Even though they used an outdated and subpar modem for sim 2, it is still capable of data. Their Zenfone Selfie does contain a dual active dual sim with lte on both sims this their "flagship" phone however used inferior hardware.
Unfortunately this may not be the phone for you in particular if you live in an area such as the U.S. or in Europe where they are shutting down 2G, it's already happening. This "flagship" dual sim phone will soon become a single sim for many of us.
I've actually talked to Asus about this and was told this is their "Flagship" phone and it is "Premium LIKE". I asked what he meant by "Premium Like" and he said it was comparable to other high end phones with compromises made on using lessor hardware. LOL, it's a knock off then, no different than buying "Prada" bags out of someones car trunk. I've had to deal with Asus on a couple of issues with their phone and have to say, I would NEVER buy anything again from them.

[Q] Dual Sim different carriers

I am planning on getting the zenfone 2 until I became questioning. I have a personal phone on wind and a business phone on telus, and I need to know if the dual Sim will support that. One of them will be the data but both numbers are gonna be used. I can set up call forwarding. Will this configuration work? Thank you
PS. This is for 2 gig 1.8 GHz version

Provided the sim you use for data is in sim slot 1 and you don't want anything other than talk and sms on sim 2. It should be fine. The sim in the 2nd slot must be able to support 2g.

I need the telus one to support 2g then? How do I check of it is supported

Ask them? I'm on a 3 and 4g only network for one sim and that has to be in slot 1. Won't work in sim 2 at all. The other sim is an EE UK sim and that works fine in both slots.

Data access on 2nd sim with 3 subscription

Was wondering if anyone here with a 3 subscription in Ireland or the UK can use data on the 2nd sim when abroad (with the 3 sim in slot 1)? I'm currently a 3 customer and had an LG G4 dual sim phone before and it wasn't possible to use 3G or 4G on the 2nd sim because 3 can't run on 2G or Edge. So the 3 sim always had to have data access enabled.

You can only have data access on one sim at a time. You can switch which sim has the data access but the one with data access will have 4g/3g/2g and the other sim will be 3g/2g. I use EE and Three in mine both are able to get a signal and use calls and texts. EE is the data sim on mine and Three can still make and receive calls and texts.

I used to have this problem with my dual sim HTC M8 - because only one sim could be run in 3G/4G.
Be reassured, I now can run a 3 sim happily as second sim, the OP3 allows the second sim to run in 3G.

Many thanks for the replies! Just wanted to make sure I can use the local sim for data access as the 3 Like Home option is not very good for data speed
