Someone asked me why I don’t use dual-SIM phones instead of carrying 2 or 3 phones at a time. I said that if there were only high-end phones that support dual-SIM, I might consider using them. So the question popped up — why aren’t dual-SIM phones picking up?
They’ve been here for years, even started with custom modules for Nokia 5110 and 6110 many years ago (the one that you turn off and on whenever you want to switch active SIM).
Even today, there are very few manufacturers and even phone models that support dual-SIM. Of course, that does not include those Chinese phones that offer triple-SIM and the likes.
Philips has the Xenium 9@9w and 969 while Samsung has the SGH-D780, D880 and D980 DuoS. Filipino company Solid Group is also the one distributing the my|phone dual-SIM phones. Verzio also has the Duplii and Twinn. Aside from these, we haven’t seen similar ones by LG, Sony-Ericsson and Nokia.
That’s probably because of some good reasons:
- Dual-SIM phones need to carry 2 separate transceivers for each SIM and that could easily drain the battery life of the phone (estimated to be between 30-40% lower). That also means phone manufacturers need to increase battery capacity to deliver the same standard usage and that costs more money.
- Supporting 2 SIM cards into a single phone may drastically affect volume of phone sales especially to people who tend to use 2 or more mobile numbers at the same time.
- Telcos might not want to subsidize a phone that a post-paid customer can easily add a competing SIM card into.
i was waiting for a comment that will tell about the phone’s durability. i am looking at buying samsung gt-b7722 touch dual sim. are branded dual sim phones considered as china phone? any fair comment/recommendation (based on actual use) before i buy?
Guys and Gals,
You should try Verzio Duplii Exec series!
Inexpensive and very functional!
Nice 3MP also and with 2GB memory card!!
i’ve notice that all 3 reasons are for the phone manufacturer and not for the consumer. I think that dual sim phones has a market in the philippines. currently, solid corporation the manufacturer of myphone is leading in selling dual sim phones.
Yun Verzio Duplii Gamit ko padin, however di ako satisfied…
1. If used often mabilis ma low batt.
2. the headset is ugly
3. the phone is slow
4. not user friendly
5. phone is heavy
I am thinking of getting a Cherry Mobile or a Samsung D880
iam using a Samsung D980 touch screen dualsim. napakatipid with my globe and PLDT sim. My billing drop by almost 50%. sulit talaga
I am using a MyPhone dual sim cp because i became tired of bringing with me 2 cellphones. maganda naman ang MYPhone kasi may 1 year warranty at ang battery pwede ung sa Nokia BL-4C. no probs naman so far. dapat kasi practical sire ng cp ang tingnan natin at hindi ung aesthetics. eh kung mawala man itong cp ko, di naman masakit kasi barato lng 3thou lng bili ko. unlike b4 i sued to have Nokia 6680 at 7210 supernova
i have verzio twinn and i still using it for more than 2 years na, the other dual sim cannot recieve call na magkasabay matatawagan ang dalawang sim. ang twinn kahit sabay tawagan ang dalawang sim maaccept mo pa rin yung call. lupet dava?
I have been using the Duplii for 3 months it’s just a good phone, some text some call… In use it for smart and globe phone and its also good for my sideline load business… the only thing that irritates me here is looking for contacts you hae to scroll it down manually and the phone is slow.
I am looking forward for smoe cherry mobile review… the clam shell looks great. Hopefully it also functions well.
When you have to deal with one personal cellphone and one fleet cellphone to keep track your people or answer your boss calling you on the fleet phone you can think abut dual sim one. I think that the bis phone companies do not like it so the big manufacturers go with the bigger clients.
As the big PC makers and Microsoft.
I met the Chinese 2xsim only a few weeks ago, I am using one that works very nice and looks nice too.
When I presented it to my contacts, I see a lot of interest from the public. Ignoring the issue and the Chinese may be a mistake of the big ones.
It all boils down to one word: “Firmware”.
Pag pangit, di papatulan.. :P
I’ve had the Samsung D880 for many years now and I’ve tried many others in between but somehow I cannot give up my D880.
If Samsung can only make it FASTER !!!
