This handy mobile tip am about to share with you was discovered when i wanted to remove my etisalat sim from my phone temporarily for glo because of a specific task which can only be done on the glo line at that moment. Presently the etisalat is my main sim so i was like how will i make my line ‘reachable’ for people that might wants to call me on the line?
If i asked for your advice, it would have simply be the same answer of what Alli Abiola of itsallisay.com told me which is i should insert the main sim into another phone whilst i use the glo on a seperate phone too. Though its really a good idea but the thing is, it can only work for people that are using 2 mobile phones or a dual-sim one in which am not either of the category mentioned above;)
Luckily i was able to find a shortcut and this was how am able to do it.

I just apply the Law of Redirection formulated by me which states that “If two or more things are to work as one; we have to incorporate co-operation amongst them thus making it possible to join forces with the other or one another, thereby allowing them to function as ‘One”. .
This Law was also the one i used to explain earlier as the way to link custom domains to each other.

Don’t get bored nor confused by the law i expatiate above as “your not knowing it” doesn’t mean you won’t be able to do it, Now Lets go.
