This of course common for companies like Nokia who need to market their outdated and old engineering prior to they get to the new stuff so to speak. a lot more importantly maybe the fact that it is not only in the developing planet people use two mobile phones and thus could use a dual sim phone but I really feel a lot more importantly the manufacturers themselves do NOT like to produce a dual sim phone as they always wish we, the customer buy two mobile phones instead. But then again, why should a producer care about what the customer wants.
Instead they are of course a lot more interested in advertising customer service rather than delivering it. We need to keep in mind that those people companies are not Audi advance through engineering and, what Audi forgot to say is but they do listen to the customer. They the mobile device manufacturers do not seem to have feeling or marketing data that is sufficient for them to evaluate the business crowd which will want a dual sim phones simply because we vacation and do not wish to use our residence nation sim for and in a going to country. thus we typically buy a prepaid card in the temporary host nation or alternatively as I do, have a next everlasting number sim in Europe that i use when there.
It is fortunately just a matter of your time until the sophisticated engineering companies catch on and produce a phone that really is used in business rather than a child like life-style device. once the manufacturers realize that they can produce a high quality device targeting the business community they can indeed ask for substantially a lot more money when trading the device. I would love to see a Blackberry Touch, an iPhone or an HTC with duel sim use.
