I tried many times, but the network is always engaged.

Denedım, birçok kere, ama sebeke mesğul.....? 

Not sure where to put the ´always´

My word order is probably wrong, and corrections gratefully received

 I would put  "her zaman" at the very end but thats just me.   They will get it.

 Turkish word order from ´Manisa Turkish´

Turkish Word Order

Word order is regular, but differs from English.

1. (1) Adjectival Descriptions of Subject.
2. (2) The Subject.
3. (3) Time Clauses.
4. (4) Adjectival Descriptions of Object.
5. (5) The Object
6. - and finally -
7. (6) The Verb.

 I do appreciate this information.   What is your recommendation?  apparently since mesğul implies the "be" verb then  her zaman or daima would come after "ama". 

it is "meşgul", with g not ğ

Birçok kere denedim ama şebeke hep meşgul.

It doesn´t matter where to put "hep" or "her zaman" in the speech for here. What you need to know is just not to separated the word groups, like "annemin dedesi" "granddad of my mom". There are some words but they are a group.

...ama hep şebeke meşgul

...ama şebeke hep meşgul

...ama şebeke meşgul hep

Best one is; put the adverb before the verb (or the word which has the verb suffix to be)

"meşgul" has the hidden suffix of the verb "to be"= "is busy"

For that reason, best one is to put it just before meşgul.

Thank you very much, I guess my problem is my lack of understanding of English grammar - no wonder trying to learn Turkish is so hard!!!!

 Congratulate yourself, you asked a very good question.  Knowing English grammer may or may not help learn Turkish.

However Caliptrix has an ability to explain these things  in English grammar terminology, very impressively.  I surely appreciate his help here and always.  (now I worry about my English construction...   Allahim!)
