Dual Sim Phones

[seanraaron]

I have property in both the UK and Spain, so go to Spain a lot, I needed a Spanish number for people to call when I am over there, also when I signed up to the bank etc it was a requirement, so at the moment I have three phones.

Personal = iPhone
"Work" Phone = Lumia 435
Spanish = Very old school unlocked Samsung Note which battery lasts about an hour!

If I can combine 2 & 3 into one handset that has a cracking battery life but no functions that would save me a headache

As brilliant as removable SIMs are, I wonder if their time has come. I can't imagine a modern smartphone would be unable to accept incoming calls for multiple numbers from multiple networks as-is.

Apple SIM seems to be making some progress in this area

Interesting that it's data-only and restricted to iPad...

As I said, some progress

When I get close to my piddly data limit, I activate my second giffgaff SIM for the data.

Not that that happens very often, since I don't leave the house.

"Data only" because an iPad is not a phone. (but you get around that by using data calls, such as Tu-go)
iPad only because the phones are locked to networks (a feature requested by the networks to tie you in to a contract) when you first put a sim in them.

Far as I know 3 no longer locks iPhones when they provide them. I've not had reason to test this as I've never had an issue with their customer service or contract terms, however.

I have a Sony Xperia Z5 Premium dual just for that, private and agents.

When calling and texting you always choose which sim card to use. Data goes via sim 1, both sims active when there's mobile coverage.
Does what it says on the tin. Could be smarter about a default sim to use when texting based on history.

I understand the principle, one phone, two SIM cards so can be on different carriers, but how are the carriers prioritised?

Mine's a cheapo Nokia candy bar and the way it works is you can define for each of Call, SMS, MMS, Data, whether it goes to SIM1, SIM2, or to ask each time. That much works well at least.

Other stuff - SIM2 slot in the side without needing to take the phone apart, which is nice. Battery life is maybe 6-8 days with standby / light use, not the 35 (!) claimed. Screen is unreadable in direct sunlight. Oh, and it's a phone not a computer.

You've got two options.

Dual Active.
Phones that supports both SIM cards in parallel. These cost more but allow you to receive calls on both cards and choose which one you want to make calls with when you dial the number.

Dual Standby.
Get a cheaper phone that only ever has one SIM card active at a time. You have to manually switch between them in the phone settings. The main advantage is that you don't need to manually sward the cards out.

Good review of what's available here.

Acitve = both sims can active be used SIMULTANEOUSLY
Standy By = When one sim will be IN USE (e.g. when talking) the other will be on STAND BY.

Both the types can receive calls and does not need to be manually switched.
