Hi Sean and CA3LE,
Sean, I saw your thread over on Three's support forum - which introduced me to the excellent testmy.net website - which then brought me to your thread here!!
If it's of any help, I'm also on Three Ireland and avail of the €20 All-You-Can-Eat pre-pay offer. Furthermore, I'm in Donegal too so not too far from yourself. I don't have LTE in my area but I do have a good, clear HSPA+ signal on an un-congested, rural cell site
I'd be happy to run some tests for you on my handset if only to prove the issue you've discovered is not specific to yourself. The thread above is a little crowded so if you want, you can send on the series of tests you'd like me to conduct and I'll post the results here
