I reach out to customer service often.
EXP suddenly started working perfectly on my laptop yesterday, soon after my post about it not working.... and now this morning, zilch, nada. I find a big difference from my home in Zhejiang and my home in Shenzhen...... in Zhejiang, I have had very few issues with my phone and my China Mobile number....... and wifi also usually fine, China Telecom broadband. But it does seem weird that wifi on my phone will work perfectly, but not on my MacBook.... not sure why it would matter?
EXP is best, though, for providing links that are not blocked, to get to their website or download apps, etc.
