A few months back, I retired my Windows Phone as a daily driver. While there are things that made Windows Phone stand out, there were also a few issues I’m glad to be rid of.

For Windows Phone

1. Vibrate, Loud, and Silent Modes

Without going into the settings, I could quickly switch between three modes: silent without vibration, silent with vibration, and loud with vibration.

2. Glance Screen

Time and date, email and instant messaging statuses were few of the information that were always displayed. I didn’t even need to pick up my phone or tap the screen to see them.

3. Word Flow Keyboard

The built-in keyboard was the default for every app; therefore, I never needed to select the keyboard before I started typing. However, I could switch between Hungarian and English languages, and each used a separate dictionary (instead of a shared dictionary), which meant more reliable word prediction.

4. Live Tiles

There was no need to swipe to see actual info. Current haze level, weather forecast, currency exchange rates, and recent news were just a few of the things I could see as soon I turned the screen on.

5. Camera

Both front and rear cameras dealt with low-light conditions very well.

The control was in my hands to do burst shots when I wanted rather than when the camera decided to.

6. Calculator App

The built-in calculator app had a simple interface with a lot of functions. While I only used a fraction of the provided functions, I remember using the hexadecimal calculation quite a few times.

Against Windows Phone

1. Availability of Apps

The biggest problem was probably the lack of popular apps for the platform. In many circles, it’s not cool not to have Tinder or Instagram apps.

Also, a lot of wearables and gadgets didn’t work because no apps were created that could actually make them work.

2. Camera Remote Shooting

The fact that most remote shutters, Bluetooth or wired, do not work is not good for a lot of travelers.

3. Performance of Apps

Existing apps need to be more reliable and higher performing. Microsoft’s very own Skype performed noticeably better on other platforms than on Windows Phone.

4. Battery Life

In my experience, the battery life was far from amazing, as it lasted well less than a day.

5. Cases

Getting the right case for Windows Phone was anything but easy. Not even the Chinese market offered good ones at a decent price, so users had to compromise.

6. Dimensions

It feels a bit unfair to pick on size because most phones have about the same dimensions. However, Microsoft could and should stand out from the crowd. I really like the size of my iPhone SE.

The advantage of the dual SIM phone is that one handset can operate with two SIM cards.

Dual SIM handsets are used by different groups of people, and here are three possible groups.

Business people. Dual SIM phones allow business people to use the same handset for personal and business purposes.

Travelers. Dual SIM phones allow travelers to use the same handset with the SIM card of home country and the SIM card of the country they visit.

People living abroad. Dual SIM phones allow people living abroad to use the same handset with the SIM card of home country and the SIM card of the country they live in.

A very important point is that many dual SIM handsets can operate only in a limited way. These handsets include the Lumia phones.

When two SIM cards are used, only the one that first connects to the network can operate on 3G and 4G connection speed. The other SIM can operate on 2G connection speed only.

The highest connection speed for the first SIM is 4G while for the second SIM is 2G only.

This is not a bug instead it’s a known technical limitation of the design.

People wanting to use their handset in a country where 2G network is no longer available are the most impacted by this limitation.

The shutting down of 2G networks is something that is happening. Recently, Singapore has finished shutting their 2G networks down in April 2017. That means dual SIM Lumia phones can operate with single SIM only.

No 2G network available in Singapore so the second SIM cannot connect to any network until the first SIM is turned off.

Other countries such as Australia, Canada and United States already has begun planning for shutting down their 2G networks.

It’s an observation that in Singapore dual SIM models are not available for purchase directly from the vendor Microsoft. Customers either need to go for the single SIM model or for an export set.

Only the Single SIM model of Lumia 950 is available in Singapore.

Business people tend to travel into different countries, or even permanently stay abroad. They want to use their dual SIM phone in a way dual SIM phone should be used. In the upcoming premium device, whatever it will be called, it’s a must to have this limitation resolved to allow simultaneous connection via 4G for two SIM cards.

Currently, it seems all the dual SIM Lumia models affected by this limitation including Lumia 640 and Lumia 950.
