In the days of prepaid SIMs and multiple phones many people carry, counting the Average Revenue Per User (ARPU) based on SIM cards has pretty much become irrelevant. I am the best example that this approach doesn't work anymore. Let's make it simple and only take a look at how I use mobile networks in a single country, Germany:
- The 'currently used prepaid SIM card' in my primary phone which has good rates for telephony and small screen mobile Internet access. Network: T-Mobile, MVNO: Congstar.
- My 'I always stay the same' prepaid SIM who's phone number is known by all my friends and via
which they can reach me no matter in which country I am at the moment.
When I am in Germany, I forward all incoming calls to the currently used SIM card since the price for Internet access is too high. Network: T-Mobile, MVNO: Simplytel.
- My business SIM card, the only one that is postpaid. Network: T-Mobile
- The prepaid SIM card in my car. I have a block heater which is connected to a GSM module. In the morning and evening, I call the car to switch on the heater so my windows are de-frosted and the interior is warm by the time I arrive. Network: T-Mobile, MVNO: Simplytel.
- The prepaid SIM for notebook Internet access. I can activate 200 MB for 10 euros or 5 GB for 20 euros. Network: O2/Telefonica.
- Two prepaid SIMs for notebook Internet access in Germany (€4.95 a day) or when I travel abroad and no local offer is available (€14.95 a day). Network: Vodafone. I have two so I can lend one to guests or colleagues traveling abroad.
- One prepaid SIM to use in the mobile phone abroad for small screen web browsing and mobile e-mail in countries where I don't have a local SIM card. 19 cents for 100 kB is not exactly cheap but does the job well for mobile only use. Network: E-Plus, MVNO: Alditalk.
Altogether that's 8 SIMs and 3 mobile operators. Have fun calculating the ARPU! From a technical point of view all this is quite uneccessary, one sim card for the mobile phone, one sim card for the 3G USB notebook dongle, and one for the block heater in the car is all I would need.

Martin I am amazed at all of the SIM driven devices in Europe. A block heater?! I’m still waiting for vending machines that work on the network here in the US.
I’m astounded by this. How on Earth do you manage to keep track of what SIM card works in which country and whether it is still in credit? I used to switch SIMs but kept forgetting to forward numbers etc. I currently use a UK O2 SIM with ‘unlimited’ BlackBerry data roaming and and a ‘free’ incoming calls add-on in Europe. It’s not a solution for data on my netbook, but I try to find cheap WiFi where I can. Opera on the BB is OK for many websites plus GoogleMaps/Facebook etc are acceptable (thanks for the Opera tip by the way). Single SIM saves me hassle and friends and work can reach me where ever I am. I saw an Austrian (Orange) deal that looked good for voice calls, an call inclusive Europe-wide package – I hope we see more of those and that they include data too.
yes, SIM card management at times is not so simple but what can you do 🙂
You seem to be ideal candidate for new business idea, which may be related to something like myTelco concept …
All your SIMs somehow connected and controlled together.
More and more people start to use more than one SIM.
Anybody interested ?
