Just wondering whether choosing eSIM over standard SIM cards has any adverse impact on battery life of the S20 Ultra (and, in fact, of any S20 devices). Does eSIM radio require more battery juice than SIM radios?
The underlying scenario is:
- your carrier supports eSIM;
- you need to have at least two phone numbers registered on the S20 device;
- you also want to expand internal memory by installing a microSD card in the hybrid slot (which you cannot do when using two standard SIMs). This is especially relevant for Galaxy S20 Ultra, given that there are 2 variants (128 GB and 512 GB) but with a considerable pricing gap between them.
Thanks all!
:good:
good question and i would wonder the same but about reception
If their is a difference it is most likely negligible. I haven't seen any difference with other phones
Not too many phones support this feature as of these days. Hard to draw a clear-cut conclusion. But the fact that the eSIM chip is soldered on the phone MB may have an advantage as opposed to being a removable carrier-provided physical SIM. For instance, battery drain caused by poor contact between the physical SIM and the SIM slot or progressive wear of the SIM electrical contacts should be nonexistent.
Just saying, not sure if this is true, I am obviously not an expert in this field.
I dont think eSIM would consume many resources of battery ( Depends what network you using )
I dont know, mostly eSIM integrates its own software to work, it should consume less battery,
I lost the 2nd Physical sim option after update to OneUI 5.1. Anyone experienced the same? It's S20 Ultra SM-G988B/DS

I know adapters to get micro sims to work in sim slots exists for GSM, anyone done this with the verizon LTE sims? I plan on switching between my nexus and old tbolt a bit (going to use it as a 'beater' phone now) but the different sim sizes make that difficult..
I just had a read of this:
http://blog.rebelsimcard.com/iphone-4g-ipad-micro-sim-compatibility-news-update.htm
From what I understand the differences between the two types of sizes is only the amount of surrounding plastic. Shouldn't have any problems then as long as the chip and contacts connect.
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?

HOW to get that 2G Data service??? We get superfast 2G Service from our operator (!dea Cellular in India)

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.
Looking for Lineage support from a 5.7" - 6" screen for under $200US dual SIM if possible
Priority features: GSM (must; more bands the better), large screen, economical price, long battery, dual SIM (and in this order)
Any recommendations? (Sorry I am 4 hours into searching with not much luck and there is no feature matrix of supported phones, unfortunately.) Thanks!!

I decided to get US Unlocked version of Note10+. It has the most comprehensive LTE band compatibility among all models which benefits T-Mobile users. But I do like the dual sim option offered in other oversea models since I need to receive verification text message from another international sim occasionally.
Came across Simore Speed ZX-Twin Galaxy Note 10+ dual sim adapter. Its basically a tiny piggyback that should fit inside a case. Has anyone used similar device? How is battery consumption and LTE speed impact if any?
I looked at a video online. Looks like it works. What I cannot tell is if you can recover calls on both numbers all the time, or if the switch to the second SIM is the equivalent of removing one sim and inserting another. I have the dual SIM F/DS and both numbers make my.phonr ring any time (unless I'm on a call but I can direct the other to VM, or do a follow me to the number I'm on). I agree that it misses certain bands (which I'm sure results in me not getting great data speed in the US), but it's a compromise.
I'm having trouble finding out what type of dual SIM technology the 7T uses. Is it DSFA of DSDS? Will either one allow me to take a call from two different carriers at any time? FYI I'll be using Verizon and AT&T.
OP has always 'only' DSDS. So you can only make one call with one card at the same time.
The other card is disabled during this call.
Thank you for the info. If I am currently not on a phone call, the phone being idle, are both Sims able to receive a call at anytime?
yes, of course.

Dual SIM technology? I'm on the T-Mobile variant. I'm confused.

DSDS = Dual sim, dual standby, where you have two sims from two different carriers. When one SIM is active on a call the second goes idle. DSFA = Dual sim full standby, even if one sim is active on a call the other continues to function, although I am not certain of the mechanics of how a user handles two calls at once.
These are very popular with frequent international travelers, or when someone has a company phone and a personal phone but doesn't want to carry two devices. They really haven't caught on in the US because carriers for the most part have similar coverage and don't sell them. The carriers don't want their customers to be customers of other carriers too.
Imagine living in Belgium but frequently traveling to the UK and needing to use a mobile phone in both places. The roaming fees and long distance charges would be outrageous. With a dual sim phone a user could have a Belgium sim card and a UK sim card and be able to use the appropriate sim as needed without having to place the wear and tear on the phone doing sim swaps.
I have tried to find a dual sim phone which functions well in the US. I have a dual sim S9 from the UAE market, but for some reason the data is very slow compared to a single sim S9 for the US market. I also tried a Sonim XP8 which worked well enough until the phone figured out it was in the US and disabled the second sim slot. Apparently Sonim does not want the XP8 to function as a dual sim phone in the US.
T-Mobile has disabled the second sim card slot in the 7t, for whatever reason. I have a 7t coming from direct from the manufacturer and I am excited to see how well it works as a dual sim phone. I have a line on TMO and a line on AT&T, and I don't want to carry two devices if I don't have to.

I had no idea. So if I but a dual SIM card tray and flash the international version software on my T-Mobile variant I should be able to have dual SIM functionality?

This has been done on other model phones and should be the same with this one. It was the same price point for me so I just cut TMO out of the deal. Just be careful flashing other firmware, if you are a TMO customer you wouldn't want to loose Band 71.
