Hi Dipali,
Honestly, what goes into framing and the number part should be discussed with your seniors.
It depends on the post of the person to whom you are giving the mobile. There are companies that give mobiles to their on-site employees to stay in touch and discuss the matter over the phone. Such people will need only a basic phone, and hence a minimum costing phone can be given.
On the other hand, say a CEO; he might need a smartphone to coordinate with different people, check emails even if he is not at the desk or traveling, need to update and check information and should be given a mobile accordingly.
Again, I would suggest that you do not include an amount in number and precisely. Put down the category of the phone depending on the position so that when the prices change, there are no discrepancies.
As discussed above, it would greatly depend on the industry you serve and the nature of your work.
An ideal lifespan of an electric item is 3-5 years, depending on the model and company. But a bare minimum of 3-5 years should be the lifespan.
The company should mention that if any data is lost due to any negligence on any of the employees, it would not be a good sign. Again, any damages caused due to mishandling of the phone would attract a penalty accordingly. If the damages are irreparable, the person will have to buy a new phone.
However, if the phone is not working for any reason beyond the employee's reach, the company will take suitable actions.
The company's decision will be final in case of any confusion.
Depends on your company's budget, and I believe you should discuss this with your seniors.
I think most of the caretaking things would be easily available.
