The most prominent problem, users have to face during the end of their contract with the Network provider is the termination of their existing mobile phone number. Phone upgradation seems to be the remedy for this headache, which not only helps them retaining their old number but also let them attain a new advanced handset.

Monotony is one strange feeling which is quite obvious in a human's life. Thats why usually people get bored using the same gadget for long time. Moreover, fascination of new and more advanced things is also a general human tendency. This attraction gets more rigorous in case of mobile phones, as almost all the phone manufacturing companies are launching high end gadgets in the market satiated with jaw dropping features. This attraction many times gets transformed into the envy, when one sees a fancy and glitzy device in other's hands. Thus, soaring thrust for advancement in the features of Upgrade Mobile Phone provokes a person to opt for a new phone.

And the termination of the existing contract implied on the user is the best opportunity for him to get rid of the old mobile device, because the service providers offer a variety of mobile phones of every brand to the users. But the main worry in this whole process is that the existing phone number of the user gets terminated with the plan. It is irrelevant to mention the importance of Mobile phone number in a person's life because its just not a number but a full fledged identity. The number which a person use for a long time is circulated among many friends, family members, near and dear ones and most importantly among the professionals of different fields.

One can not afford to loose these close contacts while getting the new number. And loosing any business contact can result in hefty monitory loss, because there are several occupations such as Media, Advocacy, Entertainment, Insurance, Finance, Marketing, Sales, Public Relations, Politics etc. which are highly dependent on the communication and maintaining contacts regularly. Loosing of any important client or your senior colleague because of changing of number is a big 'NO' in professional's dictionary.

One more issue which is of concern in this whole process is that the new number which is to be issued by network providers to us may belong to some other person in the past. This happens because there are a limited amount of numbers in the stock of companies and they issue the same numbers to the new users maintaining a certain gap of time after the termination of contract by the previous user. Thus, one is likely to receive unwanted calls and messages, disturbing him at odd hours or in the moments of peace. Moreover, it is also a possibility that the previous user of new issued number might have subscribed some special services such as sports, news and weather updates etc. So one can face unexpected hike in his monthly bill.

Thus, It is very much beneficial to opt for the Upgradation of Mobile Phones Scheme offered by every network service provider in order to retain old and trustworthy Mobile Phone Number. Under these schemes, these operators have a plethora of latest mobile handsets by different brands. The process of upgradation is totally different from porting in which the network gets changed but number doesn't. In this, the customer enters into the new contract but it totally depends on his will to change to the new plan or stick with the older one. We can clearly derive that the Upgradation of Mobile Phones is a simple and convenient process of retaining old number with an advanced new gadget.
