   I have a Pi 4 on my boat in France.  It sends back monitoring   
   information like battery voltages while I'm not on the boat.   
      
   Currently it connects via a TP-Link MR200 4G router which has a   
   free.fr SIM in it.  This has worked OK for many years but I think the   
   damp must have finally got to it because last time I was on the boat   
   (in March) it was very flakey, I had to keep restarting the router or   
   even power cycling it.   
      
   I'm going out to the boat again in a few days time and I'm looking for   
   a quick and easy (and cheap) way to restore the connection while I   
   test to find out whether it's the SIM is faulty or the MR200 router.   
      
   So can anyone recommend a 4G dongle that is known to work well in a Pi   
   4?  Then I can put the free.fr SIM in that to see if the SIM is OK   
   (and there's a Free shop nearby if I need to replace it).  If the SIM   
   is OK then I'll know the problem is with the MR200 router and I can   
   replace that.
